I think that there are two distinct problems here. First, It appears that the problem has to do with etch-backports being in my sources.list, and apt-show-versions not knowing how to distinguish between the release 'etch-backports' and the release 'etch'.
It appears as if apt-show-versions looks through the Packages-files list
from the cache to get the different potential Releases files to look
through:
DB<11>
main::(/usr/bin/apt-show-versions:180):
180: foreach (@files) {
DB<11>
main::(/usr/bin/apt-show-versions:181):
181: my $release = $_;
DB<11> print @files
/var/lib/apt/lists/macaw.riseup.net:9999_backports_dists_etch-backports_main_binary-i386_Packages/var/lib/apt/lists/macaw.riseup.net:9999_debian_dists_etch_main_binary-i386_Packages/var/lib/apt/lists/macaw.riseup.net:9999_debian_dists_etch_contrib_binary-i386_Packages/var/lib/apt/lists/macaw.riseup.net:9999_debian_dists_etch_non-free_binary-i386_Packages/var/lib/apt/lists/macaw.riseup.net:9999_security_dists_etch_updates_main_binary-i386_Packages
It then steps through those @files and tries to pick the Release files
out of there, and in my case, finds the etch-backports one first, so it
begins to process that, it looks in there for a regexp matching known
releases and happens to find 'etch' in there, and decides thats the etch
release (when it is not, its actually the backports release):
DB<14> print $release
/var/lib/apt/lists/macaw.riseup.net:9999_backports_dists_etch-backports_main_binary-i386_Release
DB<17> s
main::(/usr/bin/apt-show-versions:185):
185: $archiv = `fgrep -s Archive $release` or
186: $archiv = `fgrep -s Suite $release` or
187: ($release
=~/(potato|woody|sarge|etch|lenny|sid|stable|testing|unstable|experimental)/
and $archiv = $1) or
188: $archiv = "unknown";
DB<17> s
main::(/usr/bin/apt-show-versions:190):
190: $archiv =~ s/Archive: //;
DB<17> print $archiv
etch
DB<18>
The second problem seems to be that the list of @files that is generated
is a list of *_Packages files, but you need to look through *_Release
files for the Archive/Suite information. You do that by taking the list
of @files, and doing a simple regexp:
foreach (@files) {
my $release = $_;
$release =~ s/Packages/Release/;
and then looking through that. The problem is you have to get to this
actual file:
macaw.riseup.net:9999_security_dists_etch_updates_Release
by doing that search and replace on the file:
macaw.riseup.net:9999_security_dists_etch_updates_main_binary-i386_Packages
Which wont get you anywhere, because that results in the $release being
set to:
macaw.riseup.net:9999_security_dists_etch_updates_main_binary-i386_Release
