When I run: in the docker image I get the following error:
tomb lock secret.tomb -k secret.tomb.key
tomb [W] File is not yet a tomb: secret.tomb
sha256sum: invalid option -- 'z'
Try 'sha256sum --help' for more information.
losetup: cannot find an unused loop device: No such device
basename: missing operand
Try 'basename --help' for more information.
tomb . Valid tomb file found: secret.tomb
tomb . Commanded to lock tomb secret.tomb
losetup: cannot find an unused loop device: No such device
tomb [W] Loop mount of volumes is not possible on this machine, this error
tomb [W] often occurs on VPS and kernels that don't provide the loop module.
tomb [W] It is impossible to use Tomb on this machine under these conditions.
tomb [E] Operation aborted.
I believe I followed the instructions correctly. What am I doing wrong?
What docker image are you using?
The reason for the error is an outdated sha256sum program.
I'm using the docker image given in the README.md: https://github.com/dyne/Tomb/tree/master/extras/docker.
Updating openssl does nothing, I solved it by changing ubuntu:bionic to ubuntu:fossa
