Comment 5 for bug 1718658

i have a fresh ubuntu 17.10 installation with an encrypted home (so all auto configured). If i log into my user account it all works fine. However i also get that error message in dmsg:

[ 55.425188] Could not find key with description: [...]
[ 55.425191] process_request_key_err: No key
[ 55.425191] Could not find valid key in user session keyring for sig specified in mount option: [...]
[ 55.425192] One or more global auth toks could not properly register; rc = [-2]
[ 55.425193] Error parsing options; rc = [-2]

So is this also this bug?
