[Debconf-devel] Bug#1131023: debconf: When using dialog frontend, scrollbar is missing

[Brad Barnett]

Package: debconf
Version: 1.5.91
Severity: normal

When using debconf + dialog frontend, as of trixie there is no scrollbar
on the right.

This makes it unclear whether or not there is additional text, and more
than once has caused issues during upgrades, by hiding info.  EG, what
packages to restart during an upgrade, or just text which looks whole but
is missing paragraphs unless you know you can scroll.

This bug *may* be relevant:

In as dialog seems to be a default for debconf for many installs, and in
as this literally breaks debconf, I'm reporting it here too.

Thanks
