I went into YaST / System / Services Manager and tried to start mythbackend. I got an error that I don't understand. Here's the YaST log: First I start mythbackend: 2018-07-24 12:35:04 <1> acer-suse(7430) [Ruby] clients/services-manager.rb:64 User returned `start_stop 2018-07-24 12:35:04 <1> acer-suse(7430) [Ruby] clients/services-manager.rb:240 Setting the service 'mythbackend' to active 2018-07-24 12:35:04 <1> acer-suse(7430) [Ruby] modules/services_manager_service.rb:221 Service mythbackend has been marked for activation Then I click OK: 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] clients/services-manager.rb:64 User returned `next 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] clients/services-manager.rb:88 Writing configuration... 2018-07-24 12:35:23 <2> acer-suse(7430) [ui-shortcuts] YShortcutManager.cc(checkShortcuts):85 Not enough widgets with valid shortcut characters - no check 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] modules/services_manager_service.rb:374 Saving systemd services... 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] modules/services_manager_service.rb:381 Modified services: {"mythbackend"=>{:enabled=>true, :can_be_enabled=>true, :modified=>true, :active=>true, :loaded=>false, :description=>"MythTV backend service"}} 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] modules/Service.rb:112 Enabling service 'mythbackend' 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl show mythbackend.service --property=Id --property=MainPID --property=Description --property=LoadState --property=ActiveState --property=SubState --property=UnitFileState --property=FragmentPath 2018-07-24 12:35:23 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl enable mythbackend.service 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl show mythbackend.service --property=Id --property=MainPID --property=Description --property=LoadState --property=ActiveState --property=SubState --property=UnitFileState --property=FragmentPath 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] modules/services_manager_service.rb:486 Switching services 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl show mythbackend.service --property=Id --property=MainPID --property=Description --property=LoadState --property=ActiveState --property=SubState --property=UnitFileState --property=FragmentPath 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] modules/Service.rb:140 Starting service 'mythbackend' 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl show mythbackend.service --property=Id --property=MainPID --property=Description --property=LoadState --property=ActiveState --property=SubState --property=UnitFileState --property=FragmentPath 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl start mythbackend.service 2018-07-24 12:35:24 <3> acer-suse(7430) [bash] ShellCommand.cc(shellcommand):78 Failed to start mythbackend.service: Unit mythbackend.service is not loaded properly: Exec format error. 2018-07-24 12:35:24 <3> acer-suse(7430) [bash] ShellCommand.cc(shellcommand):78 See system logs and 'systemctl status mythbackend.service' for details. 2018-07-24 12:35:24 <1> acer-suse(7430) [Ruby] yast2/systemctl.rb:32 systemctl show mythbackend.service --property=Id --property=MainPID --property=Description --property=LoadState --property=ActiveState --property=SubState --property=UnitFileState --property=FragmentPath 2018-07-24 12:35:24 <3> acer-suse(7430) [Ruby] modules/Service.rb:443 Attempt to `start` service 'mythbackend' failed.

I don't understand what "Invalid user/group name or numeric ID" means. The mythtv user is there with a userid of 471 and a description of "MythTV Backend User" and is a member of audio and video groups. (created by the system, not by me). There are no special groups. Does anybody understand what this means or how to fix it? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
