Either the comment of Michael Bienia (https://bugs.launchpad.net/ubuntu/+source/pbuilder/+bug/358264/comments/4) should fix your problem or it seems to be fixed in a more recent version of pbuilder. At least it is working correctly for me.
Could you please update to a recent version and use the correct syntax 'pbuilder <command> [flags] <dsc file>' and report back whether this solved your problem or it is still present? ** Changed in: pbuilder (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/358264 Title: --autocleanaptcache function described in man page doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pbuilder/+bug/358264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
