That appears to have been the issue -- updated w/ Portainer and it broke. I removed the container, re-installed w/ Container Manager (Synology) and its back up and running, thank you

I fixed it by editing the container PATH to: /lsiopy/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

I faced the same issue today after upgrading Calibre-web to the latest version. To fix it, all I had to do was to delete all of the environment variables expect the ones I set manually (tid, gid and tz) as well as all the labels then restart the container!
