If I install an app like a browser and the latest update version does not work can I install or fall back to an older version ?
flatpak remote-info --log flathub org.gnome.gedit
sudo flatpak update --commit=961eb64d42264cbb347acb33650bfa98d8ccdf0d69a4a6f72f328e2455f335be org.gnome.gedit
What is those command suppose to do
Install older versions? This is an example. I installed version 44.1 of org.gnome.gedit. The current version is 44.2.
How do you know the older version. for example Firefox I do not see a older version.
I can see older commits of Firefox. You have to try the commits. I like the OSTree under the hood of Flatpak:
https://docs.flatpak.org/en/latest/under-the-hood.html
The document refers to rollback but I do not see any information on how this is accomplished.
