Is there a GUI client for Linux?

Windows and MacOS versions of the submission program have GUI versions ( Is the GUI version for a Linux desktop not available, or is it just not linked on the download page?
The MusicBrainz Picard, for example, provides a Linux GUI.

Even though I’ve never used it, the acousticbrainz-gui also seems to be compatible with Linux, it’s just that a precompiled version is not made available on the AB website. Try and search if there is a package available for your distro. For example, @Freso maintains an unofficial package for Arch Linux in the AUR. You should try to find a package anyway rather than download a precompiled binary from a website, I mean, that is one of the virtues of using Linux where you can leverage an integrated ecosystem of packages. :smiley:

I have not used the gui client for years.
You should be able to download the source, cmake,make to compile.

I normally use the command line client in a screen session running on my nas as calculating can take a long time.
The client keeps track of what it has processed so you can run the client over the same directory when you add more music.
