I think I may be able to shed some light on the update working for some and not for others. (Originally I reported https://bugzilla.opensuse.org/show_bug.cgi?id=1201486) With the new 4.15.8+git.500.d5910280cc7 it restored the ability for me to login to SMB shares that required a username and password. However it still doesn't allow login to Anonymous shares. I get the same Invalid Argument issue. GUI Error reported in Nautilus is: "Failed to mount Windows share ; Invalid Argument" Connecting to a shares Anonymously does work with 4.15.5 Cheers
