Upgrading Ubuntu From Edgy to Feisty (6.10 to 7.04)

Note: This article is part of our archive and is likely out of date.
(Links may not work, downloads have not been recently tested for safety)

Ubuntu Feisty (7.04) is the latest version of Ubuntu. Here’s the quick list of new features for your enjoyment, but you should really upgrade to see everything for yourself.

New in Feisty:

  • Windows Migration Tool – Will help you migrate your user settings, such as wallpaper and bookmarks.
  • Codec wizard – Helps install unsupported codecs
  • Wireless – Greatly upgraded wireless support lets you easily connect to different networks
  • Upgraded Kernel – 2.6.20 kernel supports hardware virtualization features in the newer processors.
  • Upgraded Gnome – Gnome 2.18 has a lot of new features you’ll want, including a nice administration panel overhaul.
  • Lots of other stuff!

Note: Before you start this upgrade, you should make sure that you have updated Edgy with all the latest patches using the Update Manager. This will make installation more smooth, and also solve the problems some people are having with not being able to upgrade.

To start the upgrade from Edgy (6.10) to Feisty(7.04), you can hit the Alt+F2 combo to pop up the run box. Enter the following text. Note that the quotes are the normal double-quote.

gksu “update-manager -c”

When the Software updates tool launches, you’ll see a new button saying Upgrade. Click it. Now. Or not.

You don’t have to read the release notes before you click Upgrade again.

If you get an error message saying that authentication has failed, you will need to type the following command at the terminal prompt:


Once you get the message about entering your message now, just hit Ctrl+C and then start the install process over. If that doesn’t work, you may want to try running a shell as root before running the command ( sudo /bin/bash should do it)
Now you can click Start Upgrade. Seems that we already started the upgrade, but no matter, we’ll start it now.

You may encounter more dialogs asking to click Upgrade, if so… click upgrade. Now your system will download all the updates and install them.

All done, restart your computer by clicking the button. At least this button doesn’t say Upgrade.

To verify that you are now running Feisty, run the following command from a terminal window. Note that your output might be slightly different.

$ cat /etc/issue

Ubuntu feisty (development branch) \n \l

Check out the new Control Center goodness!

Note: If you are upgrading from Dapper (6.06) to Feisty, you will probably want to upgrade from Dapper to Edgy, and then from Edgy to Feisty.

Update:Modified the article to reflect the Feisty release.

    Hey there, really great site! I appreciate all the neat tips you put together, they’re really handy. I was wondering if upgrading Ubuntu would cause it to lose some of its settings. Like, I have a different window manager other than Gnome and I have other miscellaneous settings set and I have my system pretty much the way that I like it. Would the upgrade change any of this or will it just replace the necessary system files?

  2. The Geek

    Typically upgrading doesn’t change your personal settings, but I can’t be absolutely sure about that.

    Remember that Feisty is very beta right now, so if you use your system as your main system, you may not want to upgrade quite yet.

  3. Kevin

    Thanks! I’m actually still using Dapper, thinking of upgrading to Edgy.

  4. Chris

    Hi…great site!

    I just popped in the Live CD for Feisty Herd 2 and didn’t see the Control Center that you have pictured above…Am I missing something?


  5. The Geek


    I’m assuming the Herd2 Live CD is off an older build, which didn’t include the Control Center. I’m running the very latest available code.

  6. Chris

    Ok…Thank You.

  7. nils

    I broke my wlan driver an want so solve this problem by updateing to feisty. (New Kernel and driver…) But without internet i have to do it from the cd. Is it possible to start this upgrader from cd?

  8. The Geek

    I would not suggest upgrading to feisty with a broken wlan driver.

  9. David

    Hey, thanks for a good site. I’m having some trouble upgrading. When I click the ‘upgrade’ button, i get this error message (quote marks added): “Authenticating the upgrade failed. There may be a problem with the network or with the server.”

  10. The Geek


    What the problem is, most likely, is that the current state of the repository is broken. This is to be expected with beta software.

    You could try downloading the livecd instead.

  11. Dr.Jeckyl

    i am also having trouble with this one. when i copy and paste this: gksu “update-manager -c -d? into the Run Application box and hit Run nothing happens afterwards. any ideas? i’m really new to Ubuntu and Linux so i don’t know how to troubleshoot.

  12. The Geek


    My general thought is that you shouldn’t use Feisty if you aren’t ready to troubleshoot things. It’s going to have issues since it’s just alpha software at this point. Try out Edgy or even Dapper for best results.

  13. Dr.Jeckyl

    ok. fair enough. thanks for the great resource you provide here.

  14. geir

    I just installed Edgy two days ago and tried running this command to upgrade to Feisty.

    However it did not work on my computer, it pops up a dialogue saying “Your system is up-to-date. There are no upgrades available for you system. The upgrade will now be cancelled.”

    Do I have to add feisty repos to my sources.list before running the command?

  15. Jools

    If you copy and paste the line it doesnt work, as it does something weird with the double apostrophe.

    Itstead change the apostrophes, with std apostrophes.


  16. initech lumbar

    Great site
    i am updating now and i have to say easy to follow instructions looks great “now if only i had a better connection”

  17. kill

    Were can i find that nice control pannel? I am using the latest code.

  18. Tommi

    Hi and first of all, thanks for the great site.

    I have a problem upgrading from edgy to feisty. Well, kind of. I managed to upgrade and all, but i can only use kernel 2.6.17-10, not the newest ones like 2.6.20-9 and 2.6.20-10. I have those newest kernels in my grub loader, but when i try to use those versions, i get an error message which says something like: “Kernel alive…kernel direct mapping…tables up…and some numbers”. Then the monitor just shuts down and the computer keeps running (without doing anything, without going anywhere). Any idea what might be going on? Or do you need more information?

  19. Steve

    the instructions above have a mistake it needs to be update-manager with the -d before the -c or it doesn’t work for me at least

  20. Delbert

    The following process would also work:

    1) Edit your /etc/apt/source.list file, replacing all instances of “edgy” with “feisty”

    2) sudo apt-get update

    3) sudo apt-get dist-upgrade

    and you’re done!

  21. vikas


    Thanks for the tip about running gpg first, before upgrading!


  22. Taylor

    Anybody else not seeing the new distribution “Update” button? I’ve triple checked that I have the latest 6.10 files.

  23. Christian

    I also cannot see the “Update” button :-( Will try the manual way, as Delbert described it.


  24. ChicagoTom

    I too am not seeing the upgrade button.

    at one point it was there, and I started the upgrade. But the upgrade failed. (It wasn’t the Authentication error.) I don’t remember exactly what the error was but it seemed like it couldn’t get some repository files. — At the time I just assumed the servers were overloaded. When I came back later, and ran the Update Manager, the Upgrade button no longer shows up.

    The odd thing is that since I have another user account that has admin privelages, if I log on and run Update Manager, I see the Update Button. But since I am not sure what caused it to fail the first time, I am scared of using it for fear of the same thing happening.

    Anyone have any ideas on how to get the Update Manager to show the upgrade button. I really don’t want to burn a CD and do it that way

    Thanks in advance

  25. David

    I thought I might add that you should have all updates applied to Edgy 6.10
    before you try and upgrade the distribution to Feisty 7.04. The final release of Feisty is now out and while upgrading I read this step on Ubuntu’s site. I tried Feisty on live CD and it is looking very nice indeed.

  26. The Geek


    Thanks for the comment. I’ve been meaning to take a look at this article, now that Feisty has been released. I put in a note about updating Edgy, and I’m going to look over the article to make sure it’s still correct.

  27. MrX_TLO

    WARNING! Changes in 7.04

    The new Linux kernal merges the IDE and SCSI drivers, renaming all your /dev/hda into /dev/sda – Woe onto you if you have both types of drives! Woe unto you if you have anything that depends on hda names, etc. Oh, and hdparm is now almost totally worthless because the new driver gives errors on most settings and ignores the others. How is this is progress? This pain has yet to be felt by most other distros. Oh, the fstab wasn’t terminated by a blank like like it’s supposed to be, gives a warning but still works and easy to fix. But still.

    Also, the update breaks the closed source nvidia driver but I’m sure everyone is used to that by now. Ahem. If I had it to do over again, I would remove Beryl and the nvidia driver *before* the update because it was a royal pain afterwards.

    1 word, Envy. The new “unstable beta” version of the Envy gfx driver fixer was able to fix my gfx stuff but only after I had manually removed Beryl and the old nvidia driver and used the purge to really remove references and then set the X to the open source “nv” driver.

    Hope that helps.

  28. The Geek

    You bring up a good point… Beryl broke on my system after the upgrade. I had to reinstall it along with the drivers before I could get it working.

  29. Martin


    If you would like to know, how you can clean up your new Ubuntu 7.04 Installation, check this out:

  30. Neon

    Beryl is included with 7.04, you shouldn’t have to reinstall it. In the preferences menu there is a “desktop effects” item, which will fire up Beryl nativly. Although with this being included you’ll probably want to uninstall beryl before updating.

    Personally, having uninstalled beryl, I lost all my title bars, so had to bin it.

    The comment above about updating your repos is very important as you will need to update all your applications to work with Feisty. As mentioned in the comments above, I wouldn’t recommend upgrading from 6.10 to 7.04 just yet. Leave it a month or more if you can.

  31. Cappy

    It is Compiz that is enabled with “desktop effects”. Beryl has more effects but Compiz is more stable.

  32. Cappy

    Scratch that, it’s a stable version of Beryl.

  33. The Geek

    Actually Beryl was a fork of the Compiz project. They developed a lot more “cool” effects, but it has always been less stable.

    From what I’ve been reading, a merger is in the works to put the projects back into a single entity.

  34. Planet Malaysia

    Hopefully I got a faster bandwidth

  35. turkeybrain

    Is there any way to upgrade Edgy straight from the Feisty live CD, rather than have to download all the updates again?

    And is there a problem with having Beryl installed? Will there be any adverse effects if I don’t uninstall it before upgrading?

  36. krishna e bera

    I upgraded from ubuntu 6.10 to 7.04 and i still have my /dev/hda as well as /dev/sda partitions. The only noticeable effect was the /etc/fstab was transformed to list drives by UUID instead of device name, though the old names are in comments.

  37. Garrett

    Does upgrading from Dapper through Feisty wipe personal files..Should I backup before or will everything be fine???

  38. Slice

    i started my update manager and the error message: “Software index is broken

    It is impossible to install or remove any software. Please use the package manager “Synaptic” or run “sudo apt-get install -f” in a terminal to fix this issue at first.

    when i did the “sudo apt-get install -f” , got a message, i got this: “Reading package lists… Done

    it, (you will have to take action to change your boot loader to boot
    a new kernel), it will also remove all modules under the directory

    hi!… problem!.. I’ve just upgrade from 6.10 to 7.04, BUT in the last step (restart) the is a problem: I can’t get into Ubuntu!!… it apears the login small window, and after that the pass, then: NOTHING!.. I just can see the desktop (like light orange color) and the mouse. I only can move the mouse, and it move very slowly.

  40. Tim

    I started the upgrade on Kunbutu. I came back later (hours) and it said failed and said it would run “dpkg -cxxyyxx -a” I think. It was locked up. I erased the screen. Finally I killed the window. What do you think dpkg command was that I erased? thanks.

  41. Yvan

    I followed your suggested steps and the upgrade did work…. however I already had a full CD version of 7.04 in a drive, but I could not get the upgrade manager to look at it. Everything was downloaded again.

    I remember running into the same situation when upgrading from Breezy to Dapper before. IS there a method to make this approach work?


  42. Abhishek


    I have a Ubuntu 6.06.1 installed on my lappy. I have the new Ubuntu 7.04 DVD with me. Can I directly upgrade it via the DVD? If yes whats the process/steps?


  43. The Geek

    I’m pretty sure you can upgrade directly from the CD/DVD.

    What you’ll need to do is make sure the cdrom is selected as the primary source in the sources file (should be able to do it via the GUI, I’d imagine)

    Then you’d need to update the sources ( apt-get update ), and then try and launch the upgrade process.

    Note that I’ve not tested this out yet… I’ll try and do so in the next day or so.

  44. The Geek

    — “Does upgrading from Dapper through Feisty wipe personal files..Should I backup before or will everything be fine???”

    Upgrading will not wipe any of your personal files.

  45. Hans R.

    While upgrading to ubuntu 7.04 the Distribution Upgrade window turned blank and an error window opened blank as well. Any suggestion how to cope with this?

  46. Peter

    Unfortunately, update-manager -c crashed halfway through for me – and it had managed to update update-manager, which was now asking for PyGTK which I didn’t have installed…

    …You can continue the installation manually by doing sudo dpkg --configure -a to carry on from the console. I’m not sure if this will do the ‘cleanup’ step, as it’s doing it on my Edgy box atm.

  47. Sherry

    Thanks for the Great instructions, they worked perfectly for me. Have you written more docs with tips? Loved the Alt + F2 combo. Total noobie here.

  48. Rich

    Hi I am trying to upgrade to Ubuntu 7.04 – all goes well until I get this error message:

    Failed to fetch 404 Not Found

    and this happens every time I try to upgrade. Please could you tell me how to get past this?
    many thanks

  49. Alalykin Denis

    I am not the cool programmer or anything like that. I just so many times heard about this – and i decided to install it. Usually I run XP.
    So -now I have livecd of 6.10 and soon (but don’t know when) – get the 7.04 one. My questo is – what is better – to install 6.10 (of course – as one of two systems) and the somehow upgrade it with livecd of 7.04? Or better just to wait and install 7.04 when i get it?

  50. malvin

    The upgrade problem appears only on gnome desktop. KDE does not pose any such problem and the upgrade was effortless. Time to switch.

  51. nizaradil

    thanks very much

    good luck

  52. austin

    when i try to upgrade to 7.04
    an error comes up saying:
    Could not download all repository indexes

    The repository might be no longer available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and the correct writing of the repository address in the preferences.
    with a list of these listed: 404 Not Found 404 Not Found 404 Not Found

    wut do i do? it wont let me upgrade later either……………..
