Hi Ondrej, > your user group is gid=1000. [..] which your user is not part of.
Ah, well-spotted! So I'm now running --group-add=$MY_GROUP so I get: os.getgroups(): [27, 1000] But not only am I still seeing the same FTBFS I am seeing: grp.getgrall() filtered: [27] (I'm not sure why there is a difference between getgroups and getgrall) Regards, -- ,''`. : :' : Chris Lamb `. `'` la...@debian.org / chris-lamb.co.uk `-
