Public bug reported:
I had given up trying to recover my encrypted home directory from my
bootable USB key with ecryptfs-utils 111-0ubuntu5 and was encountering
the error below. However, seems that a change in the ecryptfs-recover-
private utility since version 107-0ubuntu1 was causing the intended
mount folder not to be created.
Passphrase:
Inserted auth tok with sig [cc0ba99aac1dcfd8] into the user session keyring
mount: /tmp/ecryptfs.PTL9aYAz: mount(2) system call failed: No such file or
directory.
ERROR: Failed to mount private data at [/tmp/ecryptfs.PTL9aYAz].
The invocation was as follows
sudo ecryptfs-recover-private /media/cefn/lubuntu-
lexar/home/.ecryptfs/cefn/.Private/
...which prompts for the login passphrase, which seems to be accepted,
but then leads to the failure to mount.
However, I tried running the same routine with the same USB key on an
older machine (originally running Vivid Vervet 15.04 and currently with
ecryptfs-utils version 107-0ubuntu1). On that system the identical
procedure successfully mounts the encrypted folder, making me think it's
a regression.
