[Samba] Can't Install Printer Drivers

[Banks, David (db2d)]

Hi All,

Wondering if anyone has seen this before. I have a new server set up with Ubuntu 18.04 with samba 4.7.6-Ubuntu and CUPS. Everything proceeds OK with connecting windows Print Manager until I try to install a driver, then I get unable to install driver error “The network name cannot be found.”

Watching the syslog on the server I get “_spoolss_AddPrinterDriverEx: move_driver_to_download_area failed - WERR_BAD_NET_NAME”.

After bumping the log level up to 10 I get no further info. So I can’t tell where it’s trying to move file to or what Net Name is bad.

Watching the path for print$ I can see a new folder created with a GUID type name — {XXXX-yy….}. This gets deleted after I hit OK on the error dialog.
