    i get this what is wrong?
    sudo sed -e ’s/\edgy/ feisty/g’ -i /etc/apt/sources.list

    sed: -e expression #1, char 1: unknown command: `

    please correct me if I did something wrong

  2. dave says:

    try to use this and check

    sudo sed -e ‘s/\sedgy/ feisty/g’ -i /etc/apt/sources.list

  3. kunchi says:

    same thing i just did:
    sudo gedit /etc/apt/sources.list

    and then used the replace function to look for edgy and replace with feisty so now it should work

    thanks not sure why the sed is not working

  4. sed command doesn’t work for me either. find/replace works fine.

  5. beijing says:

    what about upgrades using the alternate CDs? it should be another method to upgrading.

  6. jbeiter says:

    If you want to upgrade using GUI use the following command

    gksu “update-manager -c ”

    did not work at all…

    jwb@jwb-laptop:~$ gksu “update-manager -c ”
    gksu: invalid option — c
    GKsu version 1.9.3

    Usage: gksu [-u ] [options]

    jwb@jwb-laptop:~$ cat /etc/issue
    Ubuntu 6.10 \n \l

  7. admin says:

    try to use gksudo “update-manager -c “

  8. jbeiter says:

    Is there a problem with automatix or a way to get around the following fatal error?

    http://www.getautomatix.com/apt/dists/edgy/main/binary-i386/Packages.bz2: Sub-process bzip2 returned an error code (2)

    The installer keeps bombing with complaints ranging from potential network problems to protests that bzip2 is not a bzip2 file.

  9. Scriptwriter says:

    For the people who can’t get sed to work, the problem is that you can’t just copy and paste from this page. It uses the wrong quote mark. The best way to get this to work (which worked for me) is to copy the command above, paste it into your terminal, and then replace the quote marks in the command with a single quote from your keyboard.

  10. Kevin says:

    I Also get the following.

    kjames@fluffybunny:~$ gksudo “update-manager -c “
    gksudo: invalid option — c

    I did a direct cut and paste from the webpage. Is there something that needs to be installed first?

  11. Kevin says:

    OOPS. I typed mine in before reading the comment about the quotes. That fixed it for me.

  12. Jack says:

    My attempt to upgrade, whether using the GUI of command line, freezes on the following.

    Err http://packages.freecontrib.org dapper Release.gpg
    Could not connect to packages.freecontrib.org:80 (, connection timed out

  13. Jack says:

    Correction: After about 6 connection timeouts, which takes quite some time, the command line upgrade does seem to continue. Whether it’s all OK or not, time will tell.

  14. Brian says:

    After install finished all the text on the screen…and everywhere else except in terminal window is a rectangular “0” or “O”. How can I fix this? During download there were a number of programs that did not finish properly…server timed out or temporarily dropped the connection. I must be missing some necessary component.

  15. Benoit says:

    Command line method should work, but prefer using aptitude instead of apt-get (same syntax). Aptitude handles dependencies better than apt-get.
    On my installation I have Apache 2 + php 5, upgrading to apache 2.2 broke my php5 install (apache 2.2 doesn’t restart with 2.0 modules) with apt-get, and also broke the dist-upgrade process.
    So tell configurator not to restart apache, or use aptitude.

  16. RD jones says:

    Thanks, finally got updated. Tried the ‘official’ way and it hosed @ 891 files. This finished it up nicely. Again, a great big THANKS!

  17. jbeiter says:

    Once I got past automatix (figure out where to remove it from the sources list) the upgrade went through like clockwork.

    Recompiled Nvidia and everything is nice.

    VMWare is a little fussy in the aftermath. Updated with the latest bleeding edge patch and networking had to be kludged with NAT but that appears to be the biggest problem.. pretty minor IMO.

    This is a Dell 820 Laptop. Nice work guys.

    Hi all, i have a little problem with my java version, i heard the java version is supposed to be the latest java version on Ubuntu 7.04 but i checked after the upgrade(from 6.10 to 7.04) and the java version is still 1.4.2(default system-wide java version on 6.10). How can i upgrade the java version and how can i make it replace the native java version(so it will be a system-wide java instead of a local java) I need to know to make frostwire works properly.

    Tx in advance for your replies.

  19. admin says:

    You need to install the latest java packages try this

  20. Xy says:

    Already tried it and still the same thing, the newly installed java isnt usable and when i type “java -version” in terminal i still get the same thing telling me the java version is 1.4.2.

  21. admin says:

    one more option is remove java completely both the versions and install the latest version

  22. Xy says:

    I’ll try that tx. Lets cross our finguers and wish it will work.

  23. Xy says:

    GREAT It works !!! Tx for your help i realy apreciate it 🙂

    Heres my problem, I’ve install ubuntu ultimate edition base on edgy eft 6.10 and want to upgrade to 7.04 with a cd but I want to keep the interface of ultimate edition. How would I go by doing this????

    How to upgrade using the Ubuntu 7.04 Feisty Fawn CD?

    sudo apt-cdrom add
    sudo aptitude dist-upgrade

    is that all? Do I have to replace every occurrence of edgy to feisty as said in Method 2?

  26. admin says:

    follow this procedure if you want to upgrade ubuntu edgy using cdrom

    make sure you have the alternate install CD, you can save bandwidth by loading the CD into your CD-ROM drive and using
    sudo apt-cdrom add
    Perform the upgrade
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get dist-upgrade
    Just to be totally sure that everything is installed properly, run these commands
    sudo apt-get update
    sudo apt-get dist-upgrade
    sudo apt-get -f install
    sudo dpkg --configure -a
    Running dist-upgrade again is done to ensure that no packages are left to install or upgrade. In some cases, certain packages fail to install even after running dist-upgrade the second time.
    Reboot in order to effect all changes.

  27. Mamsaac says:

    I upgraded using last method (from CD) and all is perfectly working. Thanks.

  28. Sas3 says:

    I tried the last 2 methods – both without success.
    For method in (27) above, only the
    sudo apt-cdrom add
    read the cdrom (and unmounted it immediately).
    None of the other commands accessed the cdrom.
    The “dist-upgrade” did just this:

    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Calculating upgrade... Done
    The following packages have been kept back:
    0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

    The whole process was over in about a minute…
    What might I be doing wrong?
    Thanks for any help.

  29. Sas3 says:

    Oops where did that last post “30” go?

    Anyways, trying again:
    …continuing from post 29 …
    I also tried replacing all instances of “edgy” with “feisty” in /etc/apt/sources.list.

    I did list out 600+ upgrades, but it still isn’t reading from the cdrom. I tried this with the cdrom mounted, as well as unmounted (apt-cdrom had unmounted it). No luck. 🙁
