I am trying to help a user solve an issue with a bootable USB drive, but there seems to be a file whose ownership cannot be edited. I thought it would have been possible with:
sudo chown user:user ldlinux.sys
When that is executed, however, terminal gives this error:
Operation not permitted
The extended chat I had with the user can be found here.
getfacl ldlinux.sys
mount
.id
. This error can appear if your user by some reason was assigned to another group. In normal situationid
should look like thisuid=1000(username) gid=1000(username) groups=1000(username)
. You can check and change it in/etc/passwd
file as well.
