Aptitude should give priority to removing and purging packages before
handling any other package installs or upgrades. In this way, things
can be cleared out, space can be made, and complexity reduced for any
operations that follow.
This came up for me today when /usr became full during an upgrade.
Because /usr filled up, the upgrade failed, leaving the system in a
broken state, including leaving packages unconfigured and dependencies
uninstalled. However, aptitude kept trying to fix the dependency
problems whenever I tried to purge packages to free up space, trying
to do any of the fixes before the purges, which of course continually
failed because there was no space in /usr. If aptitude had purged all
requested packages *before* attempting any fixes, then there would
have been space for the fixes and they would have succeeded. Not to
mention that the removals/purges could potentially simplify any
dependency calculations needed for the fix. Ultimately I had to
remove all of the packages with unmet dependencies inorder for things
to get fixed, which is obviously not ideal.
It also in general just seems to me to make more sense to do any
removals and purges first since it reduces the overall complexity and
storage needs of the system, therefore only simplifying whatever
operations might follow.
Thanks for maintaining such a key component to Debian.
jamie.
