Some days ago I tried to install program with "pkg" on FreeBSD 12.4 without success. It seems ports library is not online for EoL versions. From this topic I had the belief that I can install EoL version and add all necessary packages (until their last update).Up to the last released updates for that version, yes. But there won't be any new patches after the EoL date.
Ports are in git, it's a version control system and allows you to jump back in history. You're talking about packages and specifically the FreeBSD package repositories, those are indeed gone because package repositories for old, unsupported, versions aren't kept around. There is an archive but this only contains packages for the stuff that was on the DVD images when that release was made.It seems ports library is not online for EoL versions.
