| ---- === Some common apt problems === I keep finding out that a number of people don't know these two things. Firstly, {{{E: Dynamic MMap ran out of room}}} errors when doing an {{{apt-get update}}} are easily resolved by adding a line to /etc/apt/apt.conf like so: {{{Cache-Limit "8388608";}}} (There's no special significance to this number AFAIK except that it represents 8MB, and has always been good enough for me. I suggest trying 16777216 if it doesn't work...) Secondly, running out of space in /var is quite common for newbie debian users. Packages downloaded by {{{apt}}} are stored in {{{/var/cache/apt}}}, so if this gets full you can end up with logging and mail delivery breaking and stuff. The solution is to either have this directory on its own partition, or to use {{{apt-get clean}}} every so often. (Note that tools like {{{dselect}}} apparently do this automatically, though) |

Debian GNU/Linux Tips
See all of dpkg -l
dpkg -l gets cutoff? Use:
COLUMNS=200 dpkg -l
or if you just want package names:
dpkg --get-selections
Keeping up with changes in packages
apt-get install apt-listchanges - I like to keep up-to-date know what's changed on my woody boxes. This emails you the diffs of upgraded packages when you run apt-get upgrade.
