Upgrade to Wheezy
Steps to be performed to upgrade from Squeeze (amd64) to Wheezy. I don't explain why a certain step is done - read the manual found at step one. You should know what you're doing!
- backup your data
- backup as recommended:
tar czf ~/squeeze-bkup.tgz /etc /var/lib/dpkg /var/lib/apt/extended_states \ /var/lib/aptitude/pkgstates dpkg --get-selections "*" > ~/dpkg-selections.squeeze
- prepare for recovery
- remove conflicting packages
- review actions pending in package manager: To perform this review, launch aptitude in “visual mode” and press g (“Go”). If it shows any actions, you should review them and either fix them or implement the suggested actions. If no actions are suggested you will be presented with a message saying “No packages are scheduled to be installed, removed, or upgraded”.
# Checking packages status dpkg --audit dpkg -l | pager aptitude search "~ahold" dpkg --get-selections | grep hold
- update the package list
- recorde the session
script -t 2>~/upgrade-wheezystep.time -a ~/upgrade-wheezy1.script
- let's go:
- make sure you have sufficient space for the upgrade
- kernel flavour selection only applicable if you're running an i386 sytem
- minimal system upgrade:
- upgrade the system:
Possible issues during upgrade
- transitioning from ia32-libs to multiarch (the ia32-libs package is now a transitional package)
- in order to allow installation of i386 packages on an amd64 system, execute the following commands:
dpkg --add-architecture i386 apt-get update apt-get install ia32-libs
- upgrade the kernel
# determine your kernel metapackage: dpkg -l "linux-image*" | grep ^ii # install kernel, e.g. apt-get install linux-image-2.6-686 # if you get an error message saying "W: Possible missing firmware ..." # you will need the nonfree firmware packages: apt-get install firmware-linux-nonfree update-grub
Reboot and we're done.
