Hi Chris, That’s nice but I’ve crawled all over the support sites and the web. Many have reported and discussed this and related problems mounting shares in 20.04 but no one has either explained the cause of the problem or offered a definitive solution.
Based on the existence of the problem and the lack of any documentation or solution leads me to conclude that this is in fact a bug and not a support issue. This reminds me of a problem that I had with a Mac that spontaneously crashed and restarted with an error code that Apple never documented and which none of the “support” staff had been “trained” on. When mount works from the command-line but not from fstab (with correct syntax) the only possible explanation is that it is a bug. The BAD_NETWORK_NAME can’t really be bad if it works in the mount command. btw - smb4k also has no problem mounting this share, but it is not persistent between reboots.
