Public bug reported: Expected: software-properties-gtk should launch properly; instead it crashes and doesn't launch.
Out of the blue, I couldn't open Software&Updates so I checked the output of software-properties-gtk which is: ``` WARNING:root:system-image-cli failed, using defaults: [Errno 13] Permission denied: 'system-ima WARNING:root:system-image-cli failed, using defaults: [Errno 13] Permission denied: 'system-ima ERROR:dbus.proxies:Introspect error on :1.159:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Traceback (most recent call last): File "/usr/bin/software-properties-gtk", line 100, in <module> app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file) File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 172, in __init__ self.backend.Reload(); File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 70, in __call__ return self._proxy_method(*args, **keywords) File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 145, in __call__ **keywords) File "/usr/lib/python3/dist-packages/dbus/connection.py", line 651, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name :1.159 was not provided by any .service files ``` If I launch it with sudo I get circa the same output: ``` ERROR:dbus.proxies:Introspect error on :1.167:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Traceback (most recent call last): File "/usr/bin/software-properties-gtk", line 100, in <module> app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file) File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 172, in __init__ self.backend.Reload(); File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 70, in __call__ return self._proxy_method(*args, **keywords) File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 145, in __call__ **keywords) File "/usr/lib/python3/dist-packages/dbus/connection.py", line 651, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name :1.167 was not provided by any .service files ``` Additional info: $ uname -r `5.3.0-51-generic` $ dpkg -l software-properties-gtk | grep ii ``` ii software-properties-gtk 0.96.24.32.12 all manage the repositories that you install software from (gtk) ``` $ apt-cache policy software-properties-gtk ``` software-properties-gtk: Installed: 0.96.24.32.12 Candidate: 0.96.24.32.12 Version table: *** 0.96.24.32.12 500 500 http://it.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://it.archive.ubuntu.com/ubuntu bionic-updates/main i386 Packages 100 /var/lib/dpkg/status 0.96.24.32.1 500 500 http://it.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 500 http://it.archive.ubuntu.com/ubuntu bionic/main i386 Packages ``` Release: Ubuntu 18.04.4 LTS ** Affects: software-properties (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876726 Title: software-properties-gtk crashes: dbus.proxies error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1876726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
