What you want is possible through apt pinning and package masking but honestly, you are a hundred years too early to even think about doing this. You say Kate is not installed on your machine - but it obviously is. How would you be receiving an update to it otherwise? It would be a new install if it was merely being pulled in via dependencies. Firefox 'looked weird' because it has switched to the new Australis interface (i.e., a bit chrome-like). You probably 'fixed' it by installing an extension or two to re-skin it to the more traditional look. Your other option was to deny the update and continue using an outdated, security hole riddled broken firefox version. This does seem to be what you're asking for: "how can I ignore critical updates to my system software for no good reason?" In the strongest possible terms, do *not* do this. Your first step is to never use the stupid GUI update tool ever again. The first thing I do on my PC every day after logging in is start a terminal and issue "runthatshit" which on my systems is always aliased: ghost@failbot:~/SRC/mozilla-central$ grep runthat ~/.bashrc alias runthatshit="sudo apt-get update && sudo apt-get dist-upgrade" I examine and process my update list every single day at a prompt, and so should you - you'll quickly get used to the file naming conventions, rate of updates, etc and will shortly be able to spot oddities, unexpected upgrades, weird things being pulled in and so on. As ever, doing things manually at the terminal gives you a lot more feedback and information than GUI tools. So go away and learn to do this. Come back when you've taught yourself everything you need to know about package maintenance, operating system dependencies and library conflicts. Then, and only then, do you get the right to start arbitrarily overriding security updates on your computer. Don't forget that by not undertaking basic OS updates you're not only exposing yourself to risks, but everyone else out there on the same internet. Sorry chief :] PS> Tom gives a good suggestion. Ignore him however, and do it manually in the shell with the "--no-install-recommends" flag to apt. Learn to do it properly, OS maintenance is far too important to half-arse. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
