Hi Bartosz, Thanks for the feedback. I had tried to uninstall Simple-Scan via Ubuntu Software Center and then re-install. Since that didn't work, I followed the directions to try and build it from source https://gitlab.gnome.org/GNOME/simple-scan but that build attempt kind of failed at the end. Simple-Scan opened at the end of the build, but then it froze up looking for the connected scanner.
I just used sudo apt-get remove simple-scan from the terminal window, wondering if that works different than uninstall from the Software Center. Interestingly enough, it said it was removing 3.28.0-0ubuntu1 I ran which simple-scan after a restart, and was surprised to see /usr/local/bin/simple-scan So then I tried to run simple-scan from the terminal and got the same error: "simple-scan: error while loading shared libraries: libcolord.so.1: cannot open shared object file: No such file or directory" When I browsed to that folder there was indeed a simple-scan executable from 2015 in that folder. I deleted the executable, re-ran which simple-scan to confirm no entry, and then reinstalled with sudo apt-get install simple-scan It appears to have installed 3.28.0-0ubuntu1 from package simple-scan_3.28.0-0ubuntu1_amd64.deb but same thing when I opened simple-scan. Nothing happened. So I ran simple-scan --debug and got this error: "[+0.00s] DEBUG: simple-scan.vala:637: Starting Simple Scan 3.28.0, PID=4623 (simple-scan:4623): Gtk-WARNING **: 08:25:59.698: Failed to register client: GDBus.Error:org.gnome.SessionManager.AlreadyRegistered: Unable to register client [+0.01s] ERROR: Settings schema 'org.gnome.SimpleScan' does not contain a key named 'page-delay' Trace/breakpoint trap (core dumped)" I don't remember installing a custom version of simple-scan.... Maybe I did. What I can say is I was running 14.04 LTS up until last year, only reason I upgraded to 18.04 LTS because I started having problems with the display driver. I upgraded straight from 14.04 LTS to 18.04 LTS via 16.04 LTS. Maybe something got lost/misconfigured in the move? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869524 Title: Simple Scan doesn't load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1869524/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
