[SOLVED] newgrp: setgid failed: Operation not permitted

awayand · 2012-08-18 03:05:55

I am trying to add myself to a new group without having to logout/login. This should work, however:

$ sudo usermod -a -G kvm
$ newgrp kvm
newgrp: setgid failed: Operation not permitted

Any suggestions welcome.

 # chmod +s /usr/bin/newgrp

or

# setcap cap_dac_override,cap_setgid+ep /usr/bin/newgrp

Looks like a package bug: newgrp was part of shadow package, now is on util-linux but is not setuid. Please file a bug.
