[SOLVED] No libapache2-mod-scgi in Debian 11 Bullseye

If you run into this problem and need libapache2-mod-scgi which is not in Debian 11 Bullseye. Then you can get it from Debian 10 by using apt download libapache2-mod-scgi on system running Buster or get it from the Debian archives on the web. A simple dpkg -i libapache2-mod-scgi_1.13-1.1_arm64.deb will install it fine and enables it in the Apache configuration. The arm64 package being the arch needed for my Pi 4 it worked on my AMD 64 system too during the testing of the procedure. If you do upgrade from Buster you are in for shock, as you see it still work, if needing to do fresh install. As those files do survive the upgrade process as nothing has a conflict to remove them, it is only on fresh install you notice it does not work anymore as they are not there to install.
