For some reason, I have a folder that I cannot read nor change its ownership. If I do a ls command, this is what I get:
drwxrwxrwx 4 myusername myusername 4096 Jan 26 20:35 media1 <--- OK
drwxrwxrwx 4 myusername myusername 4096 Jan 26 20:35 media2 <--- OK
drwxrwxrwx 4 myusername apache 4096 Jan 26 20:35 media3 <--- CANNOT READ
From what I see, it is the 4th column the problem, which is different from the other ones. I tried different commands (chown, chgrp) with sudo privileges, but with no luck.
What do I have to do to make its permissions like the other folders (media1, media2)?
