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.
