But with regard to your caveat: did you mean that apt-get predates zypper?
No, apt-get is the oldest. It was one utility out of a set of utilities. I always found it super dumb that you hat to use a completely different tool to search for a package (apt-cache, I think).
The all in one apt command was introduced by Debian 8 in 2015.
Yeah I find it weird when I see instructions that still reference apt-get.
@AndrewZabar @woelkchen really ? I discard them immediately as they seem super old
That’s not really a sensible way to deal with instructions if they’re the only ones available for a specific tool. Old does not mean anything.
