Thanks for your attention. I did a SSO login and opened this issue web page (1643544). Then did the command:
apport-collect 1643544 Package sane-backends not installed and no hook available, ignoring Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. A window pops up "no further information gathered" (see attachment) $ sudo apt-get install sane-backends says that the package cannot be found. I cannot find it in synaptic either. And this page (https://launchpad.net/ubuntu/+source/sane-backends/1.0.25+git20150528-1ubuntu2) says, that it's for USB3 "or fast recent hardware" - which is not available at my system. So - what can I do now. ** Attachment added: "Bildschirmfoto von »2017-01-13 10-52-53«.jpg" https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1643544/+attachment/4803793/+files/Bildschirmfoto%20von%20%C2%BB2017-01-13%2010-52-53%C2%AB.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643544 Title: HP Scanjet 7400c Scanner locks USB2 port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1643544/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
