I wanted to test out a more recent version of Firefox on Linux Mint 18.2, so I went over to grab the Ubuntu PPA.
I ran the installation commands (as root):
add-apt-repository ppa:mozillateam/firefox-next apt-get update apt-get install firefox
apt wouldn’t update the package, because the default package priorities (check
/etc/apt/preferences.d/*.pref) won’t allow the use of Ubuntu packages over Mint packages.
Fair enough, I created a new file
Package: firefox Pin: origin ppa.launchpad.net Pin-Priority: 900 Package: firefox Pin: release o=Ubuntu Pin-Priority: 900
And updated to the beta (currently 55.0b12).
