Unable to get SELinux context of user: Invalid argument

[lindevel]

When creating an LXC container in Virtual Machine Manager I get an error:

Unable to complete install: 'virt-bootstrap did not complete successfully'

Command 'virt-sandbox --security=inherit -c qemu:///session --name=bootstrap_1191442 -m host-bind:/mnt=/home/user/.local/share/libvirt/filesystems/container1 -- /bin/tar xf /home/user/Завантажене/rootfs.tar.xz -C /mnt --exclude dev/* --exclude */.wh.* --overwrite --absolute-names' returned non-zero exit status 1.
All extracted files will be owned by the current unprivileged user.
Passing the root_password directly via command line is deprecated and using the 'file:' selector is the recommended way to use this option.

I studied the libvirt-sandbox source code, this error is caused by the --security=inherit option (this option requires SELinux to be enabled)

I suppose YMMV but removing that option does not solve the issue. Found in /usr/lib/python3.11/site-packages/virtBootstrap/utils.py if using the virt-bootstrap-git package on Archlinux. I'm also using the same.
