Unfortunately that doesn't tell why winbind failed to start, only that it did. Since there is no smb.conf attached to this bug, I can't check that it does not contain errors.

I suggest the following:
- inspect the logs in /var/log/samba/log* to see if they have more information about the problem. These logs were not attached to this bug so I can't check.
- inspect your smb.conf for syntax errors, specially around the winbind parameters. Or run the testparm utility to do some basic checks for you.

I will mark this bug as incomplete until more information becomes available. Thanks.

Hello Andreas,

Checking with testparm as you recommended showed me the problem,

Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
handle_name_resolve_order: WARNING: Ignoring invalid list value 'hosts' for parameter 'name resolve order'
Error loading services.

The problem was in the line "name resolve order" of the smb.conf file. It had this:

name resolve order = bcast hosts lmhosts wins

I deleted the word "hosts" and now winbind starts ok. Don't really know why this happened (the "hosts" word I mean), since I haven't messed with smb.conf in quite a while, but since 18.04 upgrade I had this issue, but it seems to be fixed now.

Thanks for your help.

PS: i attached the smb.conf just in case you want to check.

Thank you for your reply Roberto - glad Andreas could help you, but in that case this is more a support case than a bug.
Marking the bug as invalid (no need to wait for it to expire).
