Hi Paul,

No, it's no regression in this case:
Screen's behaviour hasn't changed at all. But it's long-standing
behaviour relies a lot on which termcap definitions are available, and
that depends on ncurses-term being installed or not on the remote (and
partially also on the local) side as well as which termcap definitions
are in ncurses-base and which are in ncurses-term. And that changes
over time. See the README "that nobody reads".
IMHO this is neither a regression nor an issue with screen's code nor
can it be fixed without causing _real_ regressions, which I'd like to
avoid.
It might be an issue with the logic implemented in screen since many,
many years if not decades. But I surely won't change such a
long-standing behaviour as a distribution-only patch.
Regards, Axel

Title:
screen 256 colour TERM setting breaks logging into older hosts
Status in gnome-terminal package in Ubuntu:
New
Status in screen package in Ubuntu:
Fix Committed
Status in screen package in Debian:
Fix Released
Bug description:
As of 16.04, the screen program started using a 256 colour setting.
The problem is that this setting is relatively new and has not had a
chance to propagate to older hosts, including something as new as the
previous 15.x release. For example:
--------------------------------------
paul@1604-host:~$ echo $TERM
screen.xterm-256color
paul@y1604-host:~$ ssh oldermachine

------------------------------------------
This makes it extremely annoying to use 16.04 in order to interact
with any other linux/unix machines. The 256 color term type needs at
least a couple years roll-out time before it becomes the default.
Otherwise the older machines won't have it and they will complain and
default to ancient crippled defaults and nag you each time they have
to do so.
