exec failed: container "xxxxx" does not exist

Hi,
I'm currently trying to install buttervolume on a dedicated server.
I followed the install guide, I can now create volume using the anybox/buttervolume:latest driver but I have some problem with the buttervolume command.
I made aliases using

alias drunc="sudo runc --root /run/docker/plugins/runtime-root/plugins.moby/"
alias buttervolume="drunc exec -t $(drunc list|tail -n+2|awk '{print $1}') buttervolume"

But when I execute, for example :

buttervolume scheduled

That return

ERRO[0000] exec failed: container "1ed2837d4ffbddc9994111b57cbfd72a972a64c77a5211099349b8f986af1bcc" does not exist

I noticed that 1ed2837d4ffbddc9994111b57cbfd72a972a64c77a5211099349b8f986af1bcc is the plugin id but I don't understand why this error is talking about container.

Thank for you help!
Have a nice day

Debian : 10.7
Kernel : 4.19.0-12-amd64
Docker : 20.10.0, build 7287ab3
Buttervolume config : default

Hi, sorry I did'nt see your issue sooner.
The container corresponding to the docker plugin seems missing. Was it installed successfully ? Do you see it active when running docker plugin ls ?
Please note that on Debian Sid currently, the root for runc containers (--root option of runc) is in /run/docker/runtime-runc/plugins.moby/ instead of /run/docker/plugins/runtime-root/plugins.moby/

Hi, thanks for your answer.
Unfortunately I reinstalled this server some weeks ago to switch to ubuntu 20.04.
But I just retried and got a similar errors, here are my logs:

celian@tss:~$ docker plugin ls

It's difficult to guess what the problem comes from, probably some other path-related or docker-related issue. It would be a good idea to write some wrapper installation script...
