Package: apt
Version: 1.2
Severity: normal
Tags: patch
User: balint@balintreczey.hu
Usertags: hardened1-linux-amd64
Dear APT Maintainers,
There are differences in architecture handling logic between dpkg and APT.
The attached patch brings APT closer to what dpkg accepts.
Please consider accepting the patch which would help bootstrapping the
musl-linux-<cpu> and hardened1-linux-<cpu> architectures.
Thanks in advance,
Balint
PS: There is a related bug, #748936, but that patch does not change
handling of CPU wildcards.
