It seems that it is unable to clone git repo via http proto from a build task repo set. If is trying to clone via git:// it is ok. Example in task 414278: git clone http://git.altlinux.org/tasks/414278/gears/100/git lapack Cloning into 'lapack'... fatal: repository 'http://git.altlinux.org/tasks/414278/gears/100/git/' not found I'm seeing two solutions either to remove line to not to temptate user with ф non-existent ability, or just to fix it like of gears' repo archive.
