I see the messages (starting with "Could not find key with description") on a fresh install of Linux Mint 19 Cinnamon.
Second line of kern.log says: "Linux version 4.15.0-36-generic (buildd@lgw01-amd64-031) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #39-Ubuntu SMP Mon Sep 24 16:19:09 UTC 2018 (Ubuntu 4.15.0-36.39-generic 4.15.18)" -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1718658 Title: ecryptfs-mount-private fails to initialize ecryptfs keys Status in ecryptfs-utils package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: ecryptfs-mount-private fails to mount the ecryptfs after the 1st reboot after creating the ecryptfs by ecryptfs-setup-private. After the unsucessful attempt dmesg contains: [ 1265.695388] Could not find key with description: [<correct key ID>] [ 1265.695393] process_request_key_err: No key [ 1265.695394] Could not find valid key in user session keyring for sig specified in mount option: [<correct key ID>] [ 1265.695395] One or more global auth toks could not properly register; rc = [-2] [ 1265.695396] Error parsing options; rc = [-2] Note: The correct key ID has been replaced in the "<correct key ID>". I also accidentally found an workaround - just running ecrytpfs- manager and then the ecryptfs-mount-private (it does not ask for password for the second time and mounts the ecryptfs correctly): host:~$ ecryptfs-manager eCryptfs key management menu ------------------------------- 1. Add passphrase key to keyring 2. Add public key to keyring 3. Generate new public/private keypair 4.
