You don't understand the problem at all. Sage overrides the system
libreadline with an older version, one that lacks features that the system
shell requires. This is a problem that affects EVERY Linux distribution
that is not terribly outdated (if I would say "it doesn't build on
Ubuntu", you would probably suddenly take this seriously, but as long as
it works on Ubuntu, it can't be not broken, right? It's not Ubuntu, so I
have to keep repeating myself, until the problem eventually also affects
Ubuntu)
As long as sage does not build its own shell for the build process,
overriding the system libreadline is simply plain stupid, and will keep
breaking again and again. In my opinion, sage should not ship its own
libreadline if the system already provides readline version 6 or newer -
eliminating all the mentioned problems.

Since when does that matter? If you must know:
