I have just installed fresh Ubuntu MATE 21.10 system.
Then I ran update-manager
manually to check and get some new updates.
It showed a surprise for me - it will remove Firefox deb-package as shown on below screenshot to replace it with Snap:
Details of updates
- Install or remove
- Duplicate packages to be removed
- Firefox Web Browser
This is not acceptable for me, I want to use normal deb-package of Firefox.
Note: actually the result does not depend on online or offline installation, the first launch of update-manager
will try to remove the Firefox deb-package.
Update 20220203 - the bug 1947501 is fixed since 20211103.
So all you need is to run the below commands:
If you need historic information - check previous revisions of this answer. But keep in mind that running
sudo apt-mark manual firefox
may be still needed if you install Ubuntu 21.10 flavor using offline installation.In Ubuntu 21.10 (Impish) Firefox is still available as a .deb package.
For Ubuntu 22.04 LTS (Jammy) you can download the latest official .deb build here: https://launchpad.net/~phd/+archive/ubuntu/firefox/
This is a PPA repository with official Ubuntu packages released originally for Ubuntu 20.04 LTS (Focal) and updated automatically as soon as a new version is released.
Remember about making a backup of your
~/.mozilla
directory before upgrading to Ubuntu 22.04.Firefox in the main (22.04) IS a snap. it's misleading, but there it is. It's what I think they call a transitional package.. doesn't actually contain the FF install, but links to the snap store... " when you try installing the deb package via apt, it just install the Snap version back!! Like Chromium, the Firefox deb in Ubuntu 22.04 is an empty package that links to the Mozilla’s official Snap." --ubuntuhandbook
or just use this ppa: https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/ppa regards
