cannot write uid_map

[donpdonp]

I wanted to try isd so I downloaded the app image and chmod 755. It errors immediately. I realize this might be fixed by giving it sudo but I wanted to try it for managing user-mode systemd services first before running a new app with sudo right away.

$ ./isd.AppImage
./isd.AppImage: cannot write uid_map: Operation not permitted
$ ./isd.AppImage --help
./isd.AppImage: cannot write uid_map: Operation not permitted

[welcome]

Thanks for opening your first issue here! 💖

Nah. There should never be a reason to use sudo, something is broken.
Can you please tell me what distro and systemd version you are using?
Thanks!

[donpdonp]

sure.
