release notes on upgrading have some info about disk space.  It's maybe
/var/cache/apt/archives taking up all your space?  I use 30 gb partitions
usually and they very rarely get over 8-10 gigs.

good luck!


I think I'm good there:

$ du -h /var
...
598M    /var

but

$ du -h /usr
...
4.2G    /usr/share
6.5G    /usr

Point well taken about removing packages though.  Thanks
