That did it for me on Xenial. root@client:~# uname -a Linux client 4.4.0-98-generic #121~lp1729337 SMP Thu Nov 2 20:53:20 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
root@client:~# mount | grep share //server/share on /mnt/share type cifs (rw,nosuid,nodev,relatime,vers=3.0,sec=ntlmssp,cache=strict,username=www-data,domain=ourdomain,uid=33,forceuid,gid=33,forcegid,addr=1.2.3.4,file_mode=0770,dir_mode=0770,nounix,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1,user) Interestingly, as FedeX pointed out, the option (unspecified in my fstab) of sec=ntlmssp has appeared as a new explicit parameter. Makes no difference to me, and it works, just FYI. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1729337 Title: CIFS errors on 4.4.0-98, but not on 4.4.0-97 with same config To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1729337/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
