Regression in Eoan: cannot print to smb connected printer

Bug #1853242 reported by Sergio Callegari on 2019-11-20

Bug Description

After upgrade from disco to eoan, notwithstanding the fact that /etc/cups/printers.conf has stayed the same, I cannot print anymore to an smb connected printer provided by my Institution.
The connection uses authentication and username, password are present in the smb url in the printers.conf file.

May be the same regression as in Fedora 30

Issue prevents upgrading to eoan.

/var/log/cups/error log repeatedly contains things like:

Session setup failed: NT_STATUS_LOGON_FAILURE
SMB connection failed!


Unable to connect to CIFS host: NT_STATUS_IO_TIMEOUT. Will retry in 60 seconds...
Unable to connect to CIFS host after (tried 3 times)

Sorry, could not report the issue from the machine where I have first experienced the bug. Also marked samba as a possible source for the issue (from the fedora report). If the issue is the same, it seems fixed in Fedora.

Running cups in debug mode (cupsctl --debug-logging) in the logs I see a couple of interesting lines:

[Job 1008] PID 2888 (/usr/lib/cups/backend/smb) stopped with status 2.
[Job 1008] Unable to connect to CIFS host: NT_STATUS_INVALID_ACCOUNT_NAME
[Job 1008] Backend returned status 2 (authentication required)

Actually not a bug, for sure not the one indicated for Fedora.
Just a very poor interaction of the Kyocera DEB package with the Disco->Eoan upgrade.

Changed in cups (Ubuntu):
status: New → Invalid
Changed in samba (Ubuntu):
status: New → Invalid
