[Bug 1774645] [NEW] mount.cifs with sec=krb5 fails with No such file or directory

[Gerald Hochegger]

Public bug reported:

ubuntu 18.04 fresh installation
cifs-utils 2:6.4-1ubuntu1

mount.cifs fails when the option sec=krb5 is given.

The error message "No such file or directory" is not very helpful.

After searching for some time for the reason, I found the /sbin/request-
key program was missing, so cifs.upcall was not called and no kerberos
key could be loaded. Installing the keyutils package fixes the problem.

Please add a dependency on keyutils to the package cifs-utils.

This is a duplicate of bug #1734700 in ubuntu 17.10 - but still present in 18.04
Bug #1772148 also needs keyutils installed when cifs-utils is installed.
