Hello Guix! I had this surprise today, after reconfiguring my Guix System with an upgraded docker:
Upon attempting to run an existing container created with the previous Docker version, I got: --8<---------------cut here---------------start------------->8--- ERROR: for moodle-docker_db_1 Cannot start service db: Unknown runtime specified /gnu/store/jx64b4nnh6yvsbp117bfjc5spqz0jfq5-runc-1.0.0-rc6/sbin/runc --8<---------------cut here---------------end--------------->8--- It seems the containers retain the exact references to the runc used, and it somehow cause the execution to fail when it doesn't match with the runc that the current Docker program is using. The workaround is to destroy the containers and recreate them from scratch on this upgraded Docker instance. Thanks, Maxim
