Samba Upgrade 18.04 - 20.04

[John T. Bryan]

Nothing particular to report, just upgrading from 18.04 - 20.04 and got this file verification error. I have no idea yet whether Samba will work now or now since the upgrade has not completed.

You seem to have a configuration error in your smb.conf:

ERROR: the 'unix password sync' parameter is set and there is no valid 'passwd program' parameter.

The default smb.conf shipped with the package has this:
(...)
# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
   unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<email address hidden> for
# sending the correct chat script for the passwd program in Debian Sarge).
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
   pam password change = yes

Status changed to 'Confirmed' because the bug affects multiple users.
