Well, Linux Mint 12 is out and it’s time to upgrade and take advantaged of the new features…
There are many ways of upgrading, as you can read here: http://community.linuxmint.com/tutorial/view/2. Please read it carefully before proceeding with the upgrade. You can turn your current installation useless.
Both are valid, but not without possible problems.
I have Linux Mint 11 transformed in a Media Center, running XBMC and connected to my Video Projector! And now, i’m ready to upgrade, using the “C2 – Packages Upgrades”.
NOTE: After altering the sources.list and start the upgrade, there’s no turning back.
Warning: I’ve tried and it didn’t work for me… I had errors about apparmor and udev… Had to install all over again… But this method is supported and i’ve tried twice (from Mint 9 to 10 and from 10 to 11) and always had worked.
Warning: It didn’t work for me. It didn’t work for me.It didn’t work for me. It didn’t work for me. It didn’t work for me. It didn’t work for me. It didn’t work for me.
This means that, i’m going to edit the file sources.list of apt, and change the sources.
First, let’s upgrade Linux Mint 11 -
After Linux Mint 11 updates itself, let’s go to update the sources.list. First, copy the file, so we can have a backup (just in case, but after you start to upgrade, there’s no turning back…)
So, i’ll transform the following lines:
deb http://packages.linuxmint.com/ katya main upstream import backport
deb http://archive.ubuntu.com/ubuntu/ natty main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ natty-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ natty-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu/ natty partner
deb http://extras.ubuntu.com/ubuntu natty main
deb http://packages.medibuntu.org/ natty free non-free
deb http://packages.linuxmint.com/ lisa main upstream import backport
deb http://archive.ubuntu.com/ubuntu/ oneiric main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ oneiric-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ oneiric-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu/ oneiric partner
deb http://extras.ubuntu.com/ubuntu oneiric main
deb http://packages.medibuntu.org/ oneiric free non-free
Basically, just alter katya to lisa and natty to oneiric
After you change the sources, let’s update the packages:
1133 upgraded, 373 newly installed, 23 to remove and 0 not upgraded.
Need to get 786 MB of archives.
After this operation, 987 MB of additional disk space will be used.
Do you want to continue [Y/n]?
Just press <enter> and let the “games” begin…
EDIT: Even if you get some errors when apt is upgrading, and the errors does not seam to be critical, ignore them and reboot the machine. After rebooting, just run apt-get upgrade and apt-get dist-upgrade so apt can update any package and configure again the “broken” configurations… I’m not saying the upgrade will work, but i’m finished and everything seems working.
