[Aptitude-devel] Bug#953402: aptitude: %i display format no more works, just displays "(pinning not available)"

[Axel Beckert]

Package: aptitude
Version: 0.8.12-3
Severity: normal

I use %i to show me in the aptitude package list which packages I have
pinned and which not.

Since at least 0.8.12-3 (maybe also 0.8.12-2, didn't check), i.e. the
patches for APT 2.0 (or linking against APT 1.9/2.0) this no more works
and even shows for pinned packages just "(pinning not available)".

Example setting from /root/.aptitude/config:

aptitude::UI::Package-Display-Format "%c%a%M%Si %p %r %9Z %8I %15v# %15V#";

Not sure if this is related to 1.9.11's

  * policy: Implement pinning by source package (Closes: #166032)

as this seems to have no direct relation as just potentially affecting
source packages. But maybe this caused some unintended collateral
damage?

Julian: Can you please comment if this is a expected change which
requires changes in aptitude or some unintended changes which needs
fixing in apt? (And if the latter is the case, maybe reassigning the bug
report and setting a proper "affects". TIA! :-)
