Description Oleg Bosis 2019-07-09 21:45:21 CEST 
Description of problem:

After upgrading MGA6 to MGA7 I can not use schroot without root privileges any more. Trying to use command

schroot -c mga7

I see the following error message:

E: mga7_64-PzhlOW-13304: Failed to lock chroot: /var/lib/schroot/session/mga7_64-PzhlOW-13304: Failed to write session file: Permission denied

(here mga7 is an alias for mga7_64 chroot environment I use).

I've compared MGA7 schroot package with MGA6 one and found that the reason for the problem is that the main executable file /usr/bin/schroot doesn't have SUID bit installed any more. If I install this bit then I can use schroot normally.

Version-Release number of selected component (if applicable):
schroot-1.7.2-12.mga7

How reproducible:
always

Steps to Reproduce:
1. try to use schroot as unprivileged user
2.
3.
