I'm not sure how we can describe this issue so that users do not get bitten by it. Specially without knowing the root cause. Maybe asking users to upgrade some services (LDAP, nss, nscd) before going to the full upgrade would be an option. > (I use NFS for apt, because my workstations have limited disk capacity, > and I have many of them, so I often download everything on one machine, and > then > remove lock, and use it on others machine to save Internet bandwidth). I would suggest, as an alternative, to use 'apt-cacher-ng' instead. You install it in one system and then make the others use it as a proxy for apt downloads. That way you do not have to handle file locking issues. > I can try reinstalling there back lenny using FAI, > and perform upgrade again to see what is going on exactly, > and record whole session. > (Previously i somehow managed to fix problem, but do not have > logs) Yes, I would appreciate that so we can take a look and try to see what's going on.
