tomb [E] Tomb file already in use: secret.tomb

I have installed version Tomb 2.9.0 on devuan beowulf stable, not from the repos i have used the release file from github.

everything seems to work thus far except when locking the tomb.

steps taken from man page.

                   tomb dig -s 128 secret.tomb

                   tomb forge secret.tomb.key

                   tomb lock secret.tomb -k secret.tomb.key

                   tomb open secret.tomb -k secret.tomb.key

when i try to lock the tomb after opening it says...

tomb [E] Tomb file already in use: secret.tomb

lsblk shows:

NAME                                                                                 MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
loop0                                                                                  7:0    0   128M  0 loop

i can manally unmount using sudo umount /media/secret and then sudo cryptsetup close tomb.secret.XXXX

But shouldn't tomb lock do these functions?

Kind regards

Hi, we have tests that verify well this basic condition, I also have tried by hand but could not reproduce. Perhaps you have something strange in your setup? please paste the output of tomb -v.

Not sure if its a typo, however in your description you mention "lock the tomb after opening" but that's not the sequence, you should lock once the tomb (upon creation) and then open/close when you like.

hi, im sorry i should have read the manual more in depth. I was of the idea that lock meant close the tomb.

It is working as it should.
