Logging in as alarm on my rpi and using su results in the following error: $this->bbcode_second_pass_code('', 'su: cannot set groups: Operation not permitted. ')
Output of ls -l /bin/su:
$this->bbcode_second_pass_code('', '-rwsr-xr-x 1 alarm alarm 63032 Feb 14 15:08 /bin/su')
I have tried to change permissions with chmod u+s /bin/su, but to no avail. Please help!
