Based on what I read of the thread, that package is progress-linux-container. $ apt-cache policy progress-linux-container progress-linux-container: Installed: (none) Candidate: 20210101-2 Version table: 20210101-2 900 800 http://ftp.us.debian.org/debian stable/main amd64 Packages 800 http://ftp.us.debian.org/debian stable/main i386 Packages 900 http://ftp.us.debian.org/debian testing/main amd64 Packages 900 http://ftp.us.debian.org/debian testing/main i386 Packages progress-linux-container is a package in Debian, and at least at a glance, is apparently meant for installing on a Debian system. (Or else it made it from the downstream distribution into upstream Debian by mistake, somehow.) It's just not meant for installing on a host system; it's meant for installing only inside a container. What resulted in it being installed in the OP's case is unclear (the OP has said he doesn't know), but at least at a glance it doesn't look like this is a case of mixing different operating systems, unless I'm misunderstanding what you mean by that. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
