    gzip: stdin: not in gzip format

    Reading package lists… Done
    E: Some index files failed to download, they have been ignored, or old ones used instead.

    As a result of this the upgrade stops.

    Ok so im updating and i get this error message:


    i have tried lots of things but nothing works

    It couldnt be to do with internet usage and the fact that my isp keeps blocking access to p2p programs could it?– just a suggestion — Keep an open mind 😉

  8. Psychoscorpic says:

    I tried the CD methods above & they failed to read the disk.
    However, I then used Synaptic.

    Simply “Add a CD-ROM” with Synaptic, point to the Alternative CD (since it has the DEB files) – et voila! It worked perfectly.
    About 45 minutes.

    Had to upgrade WINE and reinstall an app via it, but everything else works perfectly.

    For me, the upgrade using command line steps did not go smoothly.

    The problems showed up when running “apt-get -f install”

    Many packages I installed created a conflict that blocked the installation process from running to completion. Basically my entire graphical desktop was wiped out.

    The important thing was Do not use the Ubuntu 7.04 Install CD because that would possibly wipe out my /home/ directories.

    Being cautious (and extremely pissed off at my own stupidity) I backed up my entire /home/user/ directory using tar and sftp to another available computer in my home. 19 GB, ugh.

    Then I repeatedly ran “sudo apt-get -f install” and manually removed each package that was appearing in the conflicts list.

    Then I began stumbling around trying to install the packages that make graphics work. A key step was to install the x-server packages and then run:

    sudo dpkg-reconfigure xserver-xorg ; this sets your hardware and keyboard for X display

    Then, by trial and error I finally loaded a package ubuntu-desktop that gave me back the familiar graphic front end.

    Typical remove step required to make apt-get -f install show no conflicts:
    628 sudo apt-get -f remove grass grass-dev grass-doc libgdal1-1.3.2-grass qgis-plugin-grass gdal-bin libgl1-mesa-dri libmetacity0 metacity python-gnome2-desktop gedit gnome-games
    629 sudo apt-get remove acpid
    637 sudo apt-get -f install
    642 sudo apt-get remove acpi-support acpid powermanagement-interface
    643 sudo apt-get -f install
    658 sudo apt-get install ubuntu-standard
    660 sudo apt-get -f install
    700 sudo apt-get installation-guide-i386
    941 sudo apt-get install xserver-xorg
    970 sudo apt-get install xfonts-base
    973 sudo apt-get install xfonts-100dpi
    978 sudo apt-get install xfonts-75dpi
    984 sudo apt-get install ubuntu-desktop
    987 sudo apt-get -f install
    990 sudo apt-get remove acpid
    991 sudo apt-get -f install
    992 sudo apt-get install ubuntu-desktop

    I recommend a manual install into /opt after downloading the bin from Sun; the following is for Java6u1.

    sudo chmod +x jdk-6u1-linux-i586.bin
    sudo sh ./jdk*.bin
    sudo mv jdk1.6.0_01 /opt
    sudo update-alternatives –install /usr/bin/java java /opt/jdk1.6.0_01/bin/java 1
    sudo update-alternatives –install /usr/bin/javac javac /opt/jdk1.6.0_01/bin/javac 1
    sudo update-alternatives –config java
    sudo update-alternatives –config javac

    This gives you the option of having the latest version (independent of the Ubuntu repositories), and to keep multiple versions installed side-by-side for development if you require.

    Hope someone finds this useful.
