Hi,

TL;DR: apt fails where apt-get works. Why?

I just updated ASCII using apt:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I repeated it a second time, same result. At that point I noticed the last line says "maybe run *apt-get* update". Using apt everything worked (well, almost) and the packages were found; see below.

I notice that https://www.devuan.org/os/documentation/dev1fanboy/en/upgrade-to-beowulf always uses apt-get.

I used to always use apt-get myself. One or two years ago I found apt was meant to be an "easier" interface and, since it's shorter, started using that.

I guess I'd switch back to using apt-get, shouldn't I?

Best
Ale
