install previous package version

Question

I recently updated to firefox 17 during a system upgrade.

$ sudo apt-get update && sudo apt-get upgrade.

How do I revert back to a previous package version? I'd like to get back to firefox 16.0.2.

Well , I'm running Ubuntu 12.10 and I remove firefox 17 to install firefox 16.0.2.
You can try this:

1. Open a terminal and type: cd /var/cache/apt/archives
2. Search for the Firefox's 16 deb packages eg: ls -l | grep 'firefox' | grep '16.0.02'
3. In my case I have 4 deb package for firefox 16

4. Now, I removed firefox 17 with: sudo apt-get remove firefox

5. Finally I installed the firefox 16 packages with:

sudo dpkg -i `ls -l | grep 'firefox' | grep '16.0.2' | awk '{print $9}' | xargs`

Or once you have the list with the firefox 16 deb packages , you can install each .deb package with sudo dpkg -i packagename.deb

Hope this will helpful.

Regards.
