up2date.py, around line 1040 does the raise UnsolvedDependencyError seen in bugs like bug 61457, but the error string doesn't make sense. I think (not sure) that the second %s sub should be just dep and notretList[dep]. Checking the loop, since pkgs is retList[dep] from line 1024 and we never modify either, I think they'd always be the same.
Created attachment 49268 [details] yes, I *am* lame enough to supply a patch :)
yeah, looks right. Thanks for the patch.
