Issues with an older version of OpenBSD (6.8) with pkg_add and sysupgrade

Hello,

I'm a new user to OpenBSD, but I do have experience managing Linux systems.

So I'm no stranger to the command line.

Lately, I installed a server with OpenBSD 6.8.

If you're wondering why I didn't install the latest 7.4 version it is because my vps provider has some issues with that version.

So I'm basically stuck using 6.8.

To my surprise, I had great issues installing a package as simple as a text editor:

Code:srv# pkg_add nano
https://cdn.openbsd.org/pub/OpenBSD/6.8/packages/amd64/: no such dir
Can't find nanoOpening https://cdn.openbsd.org/pub/OpenBSD/ in a browser shows that only versions 7.2, 7.3 and 7.4 have packages - the server doesn't have any packages for older versions.

I did some research and found out that (apparently) OpenBSD only provides packages for the most recent versions.

It was suggested to do a Code:sysupgrade which didn't work:

Code:sysupgrade

sysupgrade: Error retrieving https://cdn.openbsd.org/pub/OpenBSD/6.9/amd64/SHA256.sig: 404 Not FoundUsing the -s flag also didn't work:

It was suggested to do a clean install with a new version (which I can't do).

I'm not looking for a fix anymore since I found a server that hosts packages for 6.8:

https://ftp.eu.openbsd.org/pub/OpenBSD/

However, I'm curious to know if that really how it is in the OpenBSD world. :scratch:
