[Aptitude-devel] Bug#782777: Cause for #782777 (recent "aptitude forget-new" issues) is likely the fix for #777760 in apt 1.0.9.8

[Axel Beckert]

Hi again,

after discussing the issue with David on IRC, we've found some more
indicators:

All affected systems so far were single arch.

Issuing "dpkg --add-architecture i386" plus "apt-get update" on an
affected amd64 system makes the symptoms vanish and aptitude works
fine again, at least with regards to the new packages list and
"aptitude forget-new".

Issuing "dpkg --remove-architecture i386" (even without "apt-get
update" afterwards) causes the packages to show up

Here's the same again on a different system where different packages
where keeping to show up in aptitude's new packages list:

[Single-Arch, with 1.0.9.8]
# apt-get install -s libgcc1-dbg
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following NEW packages will be installed:
  libgcc1-dbg
0 upgraded, 1 newly installed, 0 to remove and 2 not upgraded.
Inst libgcc1-dbg:arm64
Conf libgcc1-dbg:arm64
#

So here it is arm64 and not i386 which shows up unexpectedly on a
single-arch system.

After enabling i386 with "dpkg --add-architecture i386":

# dpkg --add-architecture i386
# apt-get install -s libgcc1-dbg
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following NEW packages will be installed:
  libgcc1-dbg
0 upgraded, 1 newly installed, 0 to remove and 2 not upgraded.
Inst libgcc1-dbg (1:4.9.2-10 Debian:unstable [amd64])
Conf libgcc1-dbg (1:4.9.2-10 Debian:unstable [amd64])
# dpkg --remove-architecture i386
# apt-get install -s libgcc1-dbg
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following NEW packages will be installed:
  libgcc1-dbg
0 upgraded, 1 newly installed, 0 to remove and 2 not upgraded.
Inst libgcc1-dbg:arm64
Conf libgcc1-dbg:arm64

So it doesn't even need the "apt-get update" to make that issue
vanish and come again.

David already seems to on to something...
