docker compose down fails due to "permission denied"
I was able to work around the problem by running:
sudo killall docker-containerd-shim
And then docker-compose down
started working for me.
I found the solution in this bug report, and it seems that it involves a backport of a fix to the runc code.
EDIT
It seems that the root cause of these problems on my system was the Docker snap image on my Ubuntu 18.04 installation. I completely removed the snap image and reinstalled Docker using https://get.docker.io, and I no longer encounter these problems. In the meantime, the rest of my answer above worked for me as a workaround.
Somehow this worked for me.
$ sudo killall containerd-shim
2021: in my case, I am using the
sudo aa-remove-unknown
then, run
sudo docker-compose down
then, the application down successfully
