How to upgrade Mint 6 Felicia to Mint 7 Gloria

Warnings:

  • This upgrade path is for the Main Edition only, from a Mint 6 Felicia to a Mint 7 Gloria system.
  • There is no guarantee that it will work for you. In fact this is quite a risky process. If you’re experienced and if you know how to troubleshoot and solve common Linux problems (in particular X11, kernel modules and APT problems) then you’re probably OK. If you’re a novice user we recommend you perform a fresh installation of Linux Mint 7 instead.
  • You should make backups of all your data before upgrading.

Upgrading graphically (easier):

  • Open a terminal and type the following commands: “apt update” and “apt install mintupgrader-felicia-main”
  • Open mintMenu and run “Menu->Administration->Upgrade to Linux Mint 7”
  • Follow the instructions. Choose the default options. Ignore errors (in particular GPG and gtk2-engines-aurora errors).

Upgrading from the command line (faster, safer):

Open a terminal and type the following commands:

  • gksu gedit /etc/apt/sources.list (Change all occurrences of “felicia” to “gloria”, and all occurences of “intrepid” to “jaunty” then save the file and close the editor)
  • apt update
  • apt remove mintassistant
  • apt install linuxmint-keyring
  • apt update
  • apt install mint-info-main (choose “Y” or “I” to install the package maintainer’s version)
  • apt install mint-meta-main(choose “Y” or “I” to install the package maintainer’s version)

In the terminal, repeat the following commands until both show no upgrades available:

  • apt upgrade
  • apt dist-upgrade

Then type the following commands:

  • apt install mint-meta-main
  • sudo rm -rf /boot/gfxmenu/default.message
  • sudo ln -s /boot/gfxmenu/linuxmint.message /boot/gfxmenu/default.message

Finally, open “Login Window” from the menu, click on the “Local” tab and choose the Arc-Wise theme. (If after rebooting you get an error about the theme at the login prompt, repeat this step.)

To get GDM to play the default Linux Mint sound, open “Login Window”, click on the “Accessibility” tab, and set the sound for “Login screen ready” to “/usr/share/sounds/linuxmint-gdm.wav”.
