It's not as simple as that, I can mount cifs shares just fine on 18.04 without having keyutils installed. I tried the exact same command line as in comment #1, bar the username/domain, against a synology DS216 NAS, and it worked just fine:
$ sudo mount -t cifs //ds216.lowtech/downloads --verbose -o vers=3,username=andreas,sec=ntlmv2,uid=1000,gid=10000,iocharset=utf8,domain=LOWTECH,nounix Password for andreas@//ds216.lowtech/downloads: ************* mount.cifs kernel mount options: ip=10.10.1.5,unc=\\ds216.lowtech\downloads,vers=3.0,file_mode=0644,dir_mode=0755,vers=3,sec=ntlmv2,iocharset=utf8,nounix,uid=1000,gid=10000,user=andreas,domain=LOWTECH,pass=******** $ mount -t cifs //ds216.lowtech/downloads on /ds216/downloads type cifs (rw,nosuid,nodev,noexec,relatime,vers=3,sec=ntlmv2,cache=strict,username=andreas,domain=LOWTECH,uid=1000,forceuid,gid=10000,forcegid,addr=10.10.1.5,file_mode=0644,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1,user) Do you guys have a pam module or something else storing keys in the kernel keyring, which cifs-utils is trying to use in your case? Try "keyctl show", as root and as your user. Something else you could try is enabling cifs debugging, as outlined here: https://wiki.samba.org/index.php/LinuxCIFS_troubleshooting#Enabling_Debugging The first two "echo" commands fail here, but the one to cifsFYI works, and produces a bit more information in dmesg. Let's see if any of this helps us get to the root of the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772148 Title: Mount.cifs does not work without keyutils being installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/1772148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
