This still isn't working right, at least not for me. I'm trying to
upgrade the release from 16.04 to 18.04 installed on Google Compute
Engine. Is it a different bug or am I missing something?

Thanks to Brian for his patience with the remote debugging session via
Launchpad comments. And for the resulting HOWTO for reproducing the
issue. :-)
Given that Stretch's screen package is without libutempter, too, this
might bite Debian with Stretch to Buster upgrades inside screen, too.
I'm

Axel (sorry about that),
I was confused about what order (installing the new binary vs running
the preinst) things happened in. Checking the perms for 2755 in the
preinst does work.

No. I said into _pre_inst, not postinst, so that everything is in

Alex - I don't think that will work because when the new version of
screen is unpacked the permissions are 755, so the check would need to
be for 755, not 2755.

Ah! That's due to switching to use libutempter. We're getting quite
close to the issue.

Thanks. This is indeed not the expected setting.

/run/screen has the following permissions
drwxrwxr-x 3 root utmp60 Jul 19 06:06 screen
screen-cleanup is a masked service in response to bug 1462692, so the
permissions of /run/screen are never changed in Ubuntu 16.04.

One could also follow these simple steps to recreate the bug.
1) Start screen on Ubuntu 16.04
2) Download bionic's screen
3) Run 'sudo dpkg --unpack screen_4.6.2-1_amd64.deb'
4) try to reattach to screen

I've been able to recreate this during a distribution upgrade from 16.04
to 18.04 (directory permissions switched from 775 to 777) when the
package is unpacked but not yet configured. This could end up causing an
issue at a conffile prompt for a different package if your screen
session (which the

I currently don't see that clobbering, at least
I believe this is a bug in screen. The postinst script has code to
handle the changed requirements for /run/screen permissions, but then
immediately afterwards a debhelper code snippet runs which clobbers them
again.
