Traceback (most recent call last): File "/usr/lib/python3/dist-packages/landscape/sysinfo/sysinfo.py", line 99, in run result = plugin.run() File "/usr/lib/python3/dist-packages/landscape/sysinfo/network.py", line 36, in run device_info = self._get_device_info() File "/usr/lib/python3/dist-packages/landscape/lib/network.py", line 163, in get_active_device_info speed, duplex = get_network_interface_speed( File "/usr/lib/python3/dist-packages/landscape/lib/network.py", line 249, in get_network_interface_speed res = status_cmd.tostring() AttributeError: 'array.array' object has no attribute 'tostring' ``` Upon investigation, `tostring()` method in Python array was deprecated in 3.9 (The default Python version in 21.04?) On 20.10: ``` Python 3.8.6 (default, Jan 27 2021, 15:42:20) [GCC 10.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from array import array >>> array('B').tostring() b'' ``` On 21.04: ``` Python 3.9.4 (default, Apr 4 2021, 19:38:44) [GCC 10.2.1 20210401] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from array import array >>> array('B').tostring() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'array.array' object has no attribute 'tostring' ``` The fix would simply be replacing `tostring()` with `tobytes()` `tostring` was deprecated since Python 3.2, and was removed in 3.9 https://docs.python.org/3.8/library/array.html#array.array.tostring PS: I have upgraded my installation from 20.10 instead of brand new installation of the 21.04 release ISO. Not sure if that changes anything, the source I find here still uses `tostring()` https://packages.ubuntu.com/source/hirsute/landscape-client >From apt-cache policy: ``` landscape-client: Installed: (none) Candidate: 19.12-0ubuntu9 Version table: 19.12-0ubuntu9 500 500 http://ca.archive.ubuntu.com/ubuntu hirsute/main amd64 Packages ``` ** Affects: landscape-client (Ubuntu) Importance: Undecided Status: New ** Patch added: "network.patch" https://bugs.launchpad.net/bugs/1925974/+attachment/5491620/+files/network.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925974 Title: Ubuntu 21.04 (Hirsute) MOTD network section is broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/landscape-client/+bug/1925974/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
