There are a lot of words about the MySQL upgrade on Ubuntu 10.04 (64 bit specifically, perhaps the 32bit version too?) — it just hangs:
You get the hopeful message:
Preparing to replace mysql-server-5.1 5.1.41-3ubuntu12.1
but then nothing happens and everything just hangs.
Seems like the issue is related to the install script — it’s trying to switch off mysql which may be running (but the script doesn’t get the proper reply to a stop mysql command), so the solution is as follows:
/etc/init.d/mysql start (the service mysql start did not do me any good…)
sudo apt-get autoremove && sudo apt-get autoclean
sudo apt-get install --reinstall mysql-server-5.1
