Ubuntu and Firefox upgrade
Filed Under (Free Software, Linux) by cranst on 24-09-2005
Today, I received a notification that there was an upgrade for Firefox that would advance me from 1.0.6 to 1.0.7 (Ubuntu release). I went ahead with the upgrade, but was thrown an unexpected error.
E: /var/cache/apt/archives/mozilla-firefox_1.0.7-0ubuntu0.1_i386.deb: trying to overwrite `/var/lib/mozilla-firefox/extensions.d/00classic', which is also in package firefox
This was unexpected because I’ve never had an issue with an upgrade in Ubuntu. I looked through a couple forums and ran across some different approaches to solving this problem. Of course I took the one that looked easiest. I opened Synaptic, searched for ‘firefox’ and removed both instances (firefox v1.0.6 and mozilla-firefox v1.0.6). After that, I reinstalled mozilla-firefox v1.0.7 and everything worked fine. My settings were also intact, so no worries.

I issued exactly the same problem. Unfortunately, your solution didn’t work for me, as synaptic refused to deinstall firefox and mozilla-firefox v1.0.6.
apt-get –reinstall install mozilla-firefox didn’t work either
PhiX…this may be obvious, but did you
sudo apt-get update
sudo apt-get install
?
