Why are you using those instructions instead of the official Debian ones? https://www.debian.org/releases/stable/amd64/release-notes/index.en.html > and I got to the > aptitude full-upgrade > part which seemed to hang If you read the howtoforge instructions carefully you will see that it says: Instead of using apt-get upgrade and apt-get dist-upgrade, you can also use the following commands, but please note that on http://www.debian.org/releases/wheezy/amd64/release-notes/ch-upgrading.en.html it reads "The upgrade process for some previous releases recommended the use of aptitude for the upgrade. This tool is not recommended for upgrades from squeeze to wheezy.". For me, aptitude has worked fine for all Squeeze to Wheezy upgrades so far. Therefore when you are using the "aptitude full-upgrade" part above you are explicitly going outside of the official recommended procedure. I strongly recommend the "apt-get upgrade" and "apt-get dist-upgrade" approach instead as documented in the offical Debian release notes. > I've tried > dpkg --configure -a > apt-get -f install > > but can't get anything to work. Did you forget to "apt-get update" after changing the sources.list file. apt-get update Systems can be complex with complex interactions. If every system were identical then it would be easy to test those and produce a plan that would work for everyone. So first let me say that it is hard because only your system is your system. > Here's a list of the objections, but I don't know how to solve them, short > of installing every package manually. > > If you've any ideas, I would be grateful to receive them, My official recommendation would be to follow the instructions in the release notes as that is the best complete source of knowledge on how to upgrade. I will guess that your problem here is some additional undesired source in your /etc/apt/sources.list or /etc/apt/sources.list.d/* files. Ensure you have a good system back. Reset sources.list back to Squeeze: apt-get update apt-get upgrade apt-get dist-upgrade # check removal list carefully! apt-get autoremove dpkg -l | grep ^rc apt-get purge ... find /etc -name '*.dpkg-*' -o -name '*.ucf-*' rm ... dpkg-query -W -f='${Conffiles}\n' | awk '$NF=="obsolete"{print$1}' apt-get purge ... Reset sources.list to Wheezy: apt-get update apt-get upgrade apt-get dist-upgrade # check removal list carefully! apt-get autoremove dpkg -l | grep ^rc apt-get purge ... find /etc -name '*.dpkg-*' -o -name '*.ucf-*' rm ... dpkg-query -W -f='${Conffiles}\n' | awk '$NF=="obsolete"{print$1}' apt-get purge ... As you can see I suggest cleaning to be very important. Leaving a lot of the lint behind can and does often cause real upgrade problems that does not exist on a clean system. When there is a conflict here I defer to the official Debian release notes. Bob
