It's annoying but I can't seem to reproduce this crash on my machine (arch linux).

[ripytide]

I've created a branch debug with a bunch of dbg!s added to the suspect lines of code. Could one of you run this branch and post the output? And also the output of the command it's running too: flatpak remotes --columns options,name,url

and the output of flatpak remotes --columns options,name,url:

Options Name    URL
user    flathub https://dl.flathub.org/repo/

For what it's worth I'm also on arch (although with cachyos repos enabled).

Okay so one of the lines is empty for some reason even though on my machine none of the output lines are:

> sudo flatpak remotes --columns options,name,url | lines

I've added some more dbg!() statements to the debug branch so we can see the raw output. Can you run it again? Sorry this is a bit back and forth to debug.

Also, both @Twig6943 and I only have flathub enabled for user flatpak. Might have something to do with that, no?

Ah I think I see, if you run the command with sudo on your machines I bet the output is empty, but without sudo it works. Do we need to run it both with and without sudo? I'm not sure what a standard flatpak installation looks like on different machines. When should one have to use sudo?

Not sure if --user works with sudo tbh

[Twig6943]

Yep it doesn't

[ripytide]

Okay so --user only makes sense without sudo and --system only makes sense with sudo.
And custom installations could go either way, which is complicated to support.

I'm going to change to code to use sudo for --system only and no sudo for --user and all other installations, hopefully that covers most people use-cases, and if not we can consider a more advanced solution when it crops up.

[ripytide]

Actually I've run a flatpak remote-add --system and it did it's own privilege escalation without sudo so I think we're good to just remove sudo from all commands.

[ripytide]

I've reproduced the issue and fixed it in #208, I'm going to make a patch release shortly.
