Comment 4 for bug 90546

debmirror is actually failing the gpgv check even if you have the key in your trusted keys in gpp, the problem is that gpgv looks for the keyring named trustedkeys.gpg, but if you look into your gnupg folder you just see:
pubring.gpg
secring.gpg
trustdb.gpg
...
this the reason why gpgv can not find the keys..
a workaround to fix this is tu set the option --keyring in the call to gpgv in debmirror
gpgv --keyring pubring.gpg 2>/dev/null --status-fd 1 $tempdir/dists/$dist/Release.gpg $tempdir/dists/$dist/Release|

this fixes the problem in gutsy, not sure why gpg don't create the file
rustedkeys.gpg
a change in gpg???
best regards
