You can see the uids and gid (group ids) of files and directories with the -n (" numeric ids") option of ls: $ ls -nĭrwxr-xr-x 6 1000 1000 4096 Apr 28 02:38 RetroPieĭrwxr-xr-x 7 1000 1000 4096 Sep 19 19:01 RetroPie-Setup Vice versa, you would have full access if the usernames are different but the uids are equal, say "pi" on RetroPie and "lubuntu" on Lubuntu both had the uid 1000 on their systems. you made a pi user on Lubuntu just for that. If your uid on Lubuntu is different than that of pi on RetroPie (normally 1000), you won't have write access to it even if the username on both systems is the same, e.g. Linux distinguishes users by their user id (uid).

Said in Adding roms never mind lubuntu is giving me permission denied when copying files to the retropie sd LOL
