Not all software is available as package for my Linux distribution. That's why I use flatpak for some applications. Recently, a new app version introduced a bug. It resulted in random crashes. So I looked into a way to get back to an older, more stable app version.
Identify older flatpak app versions
The command "remote-info" lists information about the app ("the.app.identifier"). It includes the update history and helps to find commit identifiers.
flatpak remote-info --log flathub the.app.identifier
Update to an older app version
With the update command, ideally run as superuser, install the version identified by the commit identifier.
sudo flatpak update --commit=thecommmitid the.app.identifier
Prevent automatic updates
If the system automatically looks for package updates, you need to mask the app. That keeps the older version installed. There is no unmask command, but an option to remove the mask later on.
sudo flatpak mask --system the.app.identifier
sudo flatpak mask --system the.app.identifier --remove
That's it for today. If you have feedback, suggestions, or questions about this post, please reach out to me on Twitter (@data_henrik), Mastodon (@data_henrik@mastodon.social), or LinkedIn.
