Simply use "sudo apt-get install <package>" to install anything that is missing. - Unless you lock the libsane1 package in apt ("sudo apt-mark hold <package>") and in Synaptic (Synaptic >> Package >> Lock Version), your next automated or manual Ubuntu update might re-install the original, unpatched libsane1 package. Those two package maintenance systems use independent locking mechanisms that are not synchronized. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1731459 Title: genesys_gl847 scanners produce a black band in scanned images on Ubuntu 17.10+, 18.04 LTS and 18.10 Cosmic cuttlefish To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1731459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
