Oh :) tnx for the access. But i think from now the backend are on
development. Im send patches to kenvandine for review ( as mentor

Yes im pull up the latest of code :) and whatprovides requires delete.


What you say i have a problem with the resolve method. Im check it.


Well on the resolve with pkcon works fine (without filters).

$ ./pkcon resolve pastebinit
available   	pastebinit-0.7-1-1                   [===============]

But with filters.

zodman at cosmogirl:~/lab/dev/packagekit/pk-orig/client
$ ./pkcon resolve --filter "installed"  pastebinit
zodman at cosmogirl:~/lab/dev/packagekit/pk-orig/client
$ ./pkcon resolve --filter "available"  pastebinit
available   	pastebinit-0.7-1-1                   [===============]
$ ./pkcon resolve --filter "~installed"  pastebinit
available   	pastebinit-0.7-1-1                   [===============]


Im seen works good tooo. On packagekitd not have error codes.

the error of:
- emitting message backend-error, 'resolve emitted package that was
~installed when the installed filter is in place'
no present.


Ok so here the output of all on the backend.
