One of the advantages of running Flatpaks is that all your installed Flatpak applications are automatically updated whenever you boot your system. And since the Flatpak application repository is kept up-to-date, that means I got Darktable 2.6 very soon after it became available.
I like the features that the Flatpak-based applications offer; not everyone does. However, if you're wanting to run the latest version of Darktable without having to jump through a lot of hoops it's a good way to go in my opinion.
This seems to be a great idea. I hadn't heard of Flatpak. So I removed DT 2.4.4 and installed flatpak DT via the Software Manager. It thinks DT is installed. But wait, there's less.
Launching Darktable from the menu leads to nothing happening. Ditto from the launcher in Software Manager. Inspection of processes shows three modules related to Flatpak but none labeled Darktable. /usr/bin has three flatpak related files, all small, but no Darktable file. I must not be paid up somewhere.
Perhaps the DT PPA needs to be removed. Perhaps I need to reboot (shades of Windows!).
Edit: Attempting to install from the flathub website seemed at first to be successful, but attempting to run DT led to a complaint, viz.
Code:
bwrap: Can't mount tmpfs on /newroot/dev/shm: No such file or directory
It seems to be expecting a file system dissimilar to what I have.
