Autoupdate with version 1.18.5.2309-f5213a238_amd64 fails because dumb-init is unsupported

[rk295]

Host OS: Linux Tag/Version: autoupdate

Steps:

1. Start a container with the autoupdate tag.

Expected:

Plex should download, install and start.

Actual:

The recently (?) released .deb (named plexmediaserver_1.18.5.2309-f5213a238_amd64.deb) fails because the container uses an unsupported init.

Just ran into this myself, and there's a thread here discussing issues with 1.18.5 in docker:

https://forums.plex.tv/t/plex-media-server-linux-installation-packaging-update-issues

From reading the thread, it sounds like this version had some issues with the preinst/postinst scripts for the Debian package that detect whether you're installing in a regular environment or a Docker environment.

Supposed to be fixed in the 1.18.6 release.

No longer seems to be a problem, the current plex media server deb (1.18.6.2368) installs fine.
