Well, now I know what happened:
$ git push --dry-run -v Pushing to git@github.com:archhaskell/cabal2arch ERROR: Permission to archhaskell/cabal2arch.git denied to peti. fatal: The remote end hung up unexpectedly
Magnus Therning has by mistake broken the x86_64 repository ... again. Instead of correcting the error, though, he tried to pretend that nothing happened and that nothing needs to be done about it. (See https://github.com/archhaskell/habs/issues/43/ for further details.) I didn't like that, so I committed a fix to HABS that bumped all $pkgrels in order to trigger a re-build. Now, unfortunately, that commit brought attention to the fact that Magnus has made a mistake -- a situation he very much wanted to avoid, so he removed my commit from the history of the HABS repository. He didn't revert it -- he actually overwrote the repository's current HEAD to make the commit invisible. Furthermore, Magnus has revoked my access to all ArchHaskell repositories on Github. Peter
