The /var/lib/mock/dist-foo-build-18-13 directory may be a hangover from 
when things were broken previously. It shouldn't be owned by user "torrent".

I'd do an "ls -l /var/lib/mock" and move any directories owned by user 
"torrent" somewhere else, then try again. If everything then works OK, 
delete the moved directories (mock should re-create these directories as 
needed).
