Is your home directory on NFS? I am getting the exact same issue. Output of dmesg:
``` [4399566.994763] audit: type=1400 audit(1537967487.910:1582): apparmor="DENIED" operation="sendmsg" profile="/usr/bin/man" pid=5981 comm="man" laddr=<redacted> lport=744 faddr=<redacted> fport=2049 family="inet" sock_type="stream" protocol=6 requested_mask="send" denied_mask="send" [4399566.995173] nfs: RPC call returned error 13
Looks like an AppArmor config issue.
