Public bug reported:
When some pinning rules are added in /etc/apt/preferences.d/ the
priority values of the rules that matches first are used.
Take this example:
Package: *
Pin: release n=raring
Pin-Priority: 990
Package: *
Pin: release o=LP-PPA-my-raring-ppa
Pin-Priority: 50
Results in all packages of my-raring-ppa to have a priority of 990.
(This can be 'fixed' by reverting these two sets of pinning rules)
Furthermore, if
APT::Default-Release "raring";
is used (default in /etc/apt/apt/config.d/01ubuntu), all raring packages
have a priority of 990 and
Package: *
Pin: release o=LP-PPA-my-raring-ppa
Pin-Priority: 50
is not working anymore to set/lower the priority of the my-raring-ppa
packages to 50.
The latter is quite a problem, as this prevents pinning from working properly
(IMO).
I do not know whether there are two problems
1) APT::Default-Release is precessed after the preferences
2) Order of pinning rules is reverse-chronological
, or that both problems have the same origin.
