Linode Staff

I've installed Guacamole as per the installation here:

However, when I go to install firefox with apt install firefox, I get an error and it fails, is there a workaround?

It looks like Ubuntu 22.04 has some issues with the default firefox package in it's repositories. To add it directly from Mozilla's PPA, you can do the following:

Remove the Firefox Snap:
sudo snap remove firefox

Add Mozilla's PPA:
sudo add-apt-repository ppa:mozillateam/ppa

Set the Mozilla PPA as a preferred source:

echo ' \
Package: * \
Pin: release o=LP-PPA-mozillateam \
Pin-Priority: 1001' | sudo tee /etc/apt/preferences.d/mozilla-firefox

Update the package database:
apt update && apt upgrade

Install the ESR release of Firefox:
sudo apt install firefox-esr

And that should do the trick! I wish I could take the credit for this, but another community member found this and it could be useful to others running into the same problem.

Thank you, solved my problem on 24.04 LTS.
