I’m trying to install the utilsplugin2 plugin in JOSM. I’ve done this before when using JOSM on Windows. There, I was able to install it and use it (I used the split object tool from it).
But on my other computer, running Fedora Linux, it isn’t working.
I find the plugin under Preferences, check its box, click “Update the selected plugins”, see it display a message telling me it installed it successfully, but then it doesn’t have an effect.
If I repeat these steps, it tells me all plugins are already up to date.
The new tools aren’t accessible in the menu (or via the keyboard shortcuts like alt-x for split object).
And when I go back to the plugins area of Preferences, it doesn’t appear to be installed. It doesn’t show up in the “Installed” list.
And if I search for it by name under the “All” list, its box isn’t checked.
The only difference I can think of between how I installed JOSM on each computer is that on Windows, I installed it via the Microsoft Store and got a slightly out of date version. On Fedora Linux, I installed it via the Software application, which tells me it’s from Flathub.
And the version I get this way is much more up to date compared to when I used it before on Windows.
I’m wondering if the fact it’s a FlatPak is causing this issue because I’ve heard of issues with platforms like Snaps, FlatPaks, etc where they don’t get full permissions to modify the disk. And maybe downloading plugins is implemented that way, where the program would need permission to download and save plugin-related files to disk.
