How to set priority for a PPA. I.e. using Firefox without SNAPD

[GreyGeek]

Interesting, @oshunluver. I noticed that you are running NEON. So am I. However, the first command in Step 2 failed.
It took forever to come back and gave me two options, continue or cancel. The first time I chose continue. No PPA was added. The second it again gave me the same msg so I canceled.
I went out to https://www.mozilla.org/en-US/firefo...t-desktop-beta and download the beta 100.0b9

EDIT:
Unfortunately, there is no way to import login names and passwords. The method that used to work, copying logins.json and key4.db from the old profile to the new one no longer works.

My firefox just updated itself and it reverted to the snap version. I purged snap again reinstalled the ppa firefox and it's back fine.

I went into about:config and changed the field app.update.auto to false. Is there anything else I need to do to stop the thing updating itself?

Note that the PPA may give a beta release of Firefox. Presently one gets version 100.

Also note that the PPA has firefox-esr - an "extended support release" of firefox.

On a fresh install of jammy I went through the steps above, except that I did not perform step 1, because I think I need to keep snaps and the snap daemon for other software.

This resulted in the problem that the menu entry and the panel widget still started the firefox snap version. I had to remove the widget, "Edit applications", and identify the snap firefox menu entry by the command being used, and change it's name to make them distinguishable. Then I could use the menu to add a new widget.

I suppose I could have removed the snap firefox only.

Fine, but Digikam is now a Snap. As the years go on more will become Snaps

Great to see a detailed explanation of how to do it. I do not have a fresh installation, so I am wondering if what I had done previously has had an impact on what I have. I noticed that my version of Firefox is 99.0.1

apt-cache policy firefox
firefox:
 Installed: 99.0.1+build1-0ubuntu0.22.04.1~mt1
 Candidate: 99.0.1+build1-0ubuntu0.22.04.1~mt1
 Version table:
    100.0+build1-0ubuntu0.22.04.1~mt1 900
       500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
*** 99.0.1+build1-0ubuntu0.22.04.1~mt1 1001
       100 /var/lib/dpkg/status

I am wondering how to get rid of 99.0.1 being at a priority of 1001 as this is stopping version 100.0 from being installed.

I now have Version 100.0 !!!!

$ apt-cache policy firefox                           
firefox:
 Installed: 100.0+build1-0ubuntu0.22.04.1~mt1
 Candidate: 100.0+build1-0ubuntu0.22.04.1~mt1
 Version table:
*** 100.0+build1-0ubuntu0.22.04.1~mt1 900
       500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
       100 /var/lib/dpkg/status

Solved by removing Firefox and then using muon to install Firefox and to my great surprise I got version 100 without snap.

Thanks.

Nice write up. Followed it without any issues. Nice to have a 'quick' loading Firefox again!

With the release of 22.04, a very popular browser - Firefox - is now only available from Ubuntu as a snap package. Many of us prefer not to use snap for various reasons, including reportedly the snap version of Firefox seems slower than it's debian packaged version.

Well if this is you, you're in luck. You can change it. In this How-To I will describe the following steps:

1. Removing snapd from your system.
2. Installing the Mozilla Team PPA and Firefox.
3. Setting the Mozilla Team PPA above the default releases.

This How-To does not come with a warranty. Your mileage may vary.
Although everything in this How-To has been tested and is reversible, I suggest making a backup before following this or any other How-To.
This How-To uses only terminal commands and I used Konsole.
This How-To assumes you are working with a new installation of Kubuntu 22.04 and will not address snap packages other than the Firefox from a default installation.

Commands to enter will look like this:
command here

and the output will follow like this:

here is the output
of the above command

These procedures can be used for other PPAs and I will explain how to prioritize a single package rather than an entire PPA if you desire .

Step 1. Removing snapd and dependencies:

sudo apt remove --purge snapd
sudo apt autoremove
sudo apt-get remove --purge libsnapd-qt1 chromium-codecs-ffmpeg-extra

At this point, you should no longer see "loop" devices in the output of lsblk. Snapd is removed along with all packages not needed.

*Note the package libsnapd-glib1 remains installed due to dependencies with pulseaudio and others.

Step 2: Install the Mozilla Team PPA and Firefox

sudo add-apt-repository ppa:mozillateam/ppa
sudo apt update
sudo apt install -t 'o=LP-PPA-mozillateam' firefox

You now have the debian packaged version of the latest Firefox release installed.
However, a full apt upgrade will replace it with the snap version again. We prevent that in the next step.

Step 3: Set the Mozilla Team PPA to higher priority.

sudo touch /etc/apt/preferences.d/99mozillateam
sudo nano /etc/apt/preferences.d/99mozillateam

Add the following to the 99mozillateam file:

Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 900

and save and exit nano. Now enter this to update apt:

sudo apt update

You now have set all packages from the Mozilla Team PPA at a higher priority than the default packages. To verify this run this command:

apt-cache policy

The output will be fairly long. Here is the first part:

Package files:
 100 /var/lib/dpkg/status
     release a=now
 900 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main i386 Packages
     release v=22.04,o=LP-PPA-mozillateam,a=jammy,n=jammy,l=Firefox ESR and Thunderbird stable builds,c=main,b=i386
     origin ppa.launchpadcontent.net
 900 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
     release v=22.04,o=LP-PPA-mozillateam,a=jammy,n=jammy,l=Firefox ESR and Thunderbird stable builds,c=main,b=amd64
     origin ppa.launchpadcontent.net

and a later part:

 500 http://us.archive.ubuntu.com/ubuntu jammy/main i386 Packages
     release v=22.04,o=Ubuntu,a=jammy,n=jammy,l=Ubuntu,c=main,b =i386
     origin us.archive.ubuntu.com
 500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
     release v=22.04,o=Ubuntu,a=jammy,n=jammy,l=Ubuntu,c=main,b =amd64
     origin us.archive.ubuntu.com
Pinned packages:

Note the Mozilla Team PPA shows a priority of 900 while Ubuntu Main (where Firefox snap version is) is at the default of 500.

Lets look at the priority of just the Firefox package:

apt-cache policy firefox

firefox:
  Installed: 100.0+build1-0ubuntu0.22.04.1~mt1
  Candidate: 100.0+build1-0ubuntu0.22.04.1~mt1
  Version table:
     1:1snap1-0ubuntu2 500
        500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
 *** 100.0+build1-0ubuntu0.22.04.1~mt1 900
        900 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
        100 /var/lib/dpkg/status

Here, note the package has a 900 priority as well as the PPA. The *** indicates this package is installed.
Also note the priority number is listed ahead of the PPA line, but trails an individual package.

You can also use the above method to lower the priority of a PPA below the default 500 so that you can install a particular package from a PPA without installing everything from it.

At this point, Thunderbird will also come from the Mozilla Team (currently one point higher version). If you wish to avoid this, you can set only the priority for the Firefox package.

To accomplish this, simply change the contents of /etc/apt/preferences.d/99mozillateam as edited above to:

Package: firefox
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 900

Then enter this again:
sudo apt update

Now the Mozilla Team PPA is at the default priority:

apt-cache policy

Package files:
 100 /var/lib/dpkg/status
     release a=now
 500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main i386 Packages
     release v=22.04,o=LP-PPA-mozillateam,a=jammy,n=jammy,l=Firefox ESR and Thunderbird stable builds,c=main,b=i386
     origin ppa.launchpadcontent.net
 500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
     release v=22.04,o=LP-PPA-mozillateam,a=jammy,n=jammy,l=Firefox ESR and Thunderbird stable builds,c=main,b=amd64
     origin ppa.launchpadcontent.net
~~~

But the Firefox package is still at the higher priority:

apt-cache policy firefox

firefox:
  Installed: 100.0+build1-0ubuntu0.22.04.1~mt1
  Candidate: 100.0+build1-0ubuntu0.22.04.1~mt1
  Version table:
     1:1snap1-0ubuntu2 500
        500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
 *** 100.0+build1-0ubuntu0.22.04.1~mt1 900
        500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
        100 /var/lib/dpkg/status

Note the difference here is the package shows 900 priority while the PPA still indicates 500.

You can add other packages from this PPA the same way, for example Thunderbird, by adding additional stanzas to /etc/apt/preferences.d/99mozillateam:

Package: firefox
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 900

Package: thunderbird
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 900

Don't forget to update apt after every edit of this file(s):
sudo apt update

The above techniques apply to any PPA or package.

Enjoy your snap free Kubuntu and Firefox!
