New here and to Linux. Seeing this after ignoring the python issue for a long time. I ignorantly upgraded to the dev branch of Ubuntu 24.04 from Ubuntu 22.04 LTS as a result of trying out do-release-upgrade blindly. (I didn't bother to look up the -d flag and what it does.)
I avoided the software-properties-gtk python issue by **deleting** the [u]older source files/entries[/u] from the /etc/apt/ folder as recommended by some above. After Software & Updates started up again: out of all the repositories I did want to add, only AnyDesk's one worked. Not only did the rest not work but those caused the app to crash. I had to manually remove the new entries/files from the /etc/apt/ folder again in order to continue opening it directly. Glad to see that it has some solution. There's a long way to go. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/2053228 Title: software-properties-gtk does not start Status in software-properties package in Ubuntu: Fix Released Bug description: On a new install with the new format sources.list software-properties-gtk does not start: corrado@corrado-n4-nn-0215:~$ software-properties-gtk 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 163, in __init__ SoftwareProperties.__init__(self, options=options, datadir=datadir, File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 109, in __init__ self.backup_sourceslist() File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 437, in backup_sourceslist source_bkp = SourceEntry(line=source.line,file=source.file) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/aptsources/sourceslist.py", line 509, in __init__ raise ValueError("Classic SourceEntry cannot be written to .sources file") ValueError: Classic SourceEntry cannot be written to .sources file corrado@corrado-n4-nn-0215:~$ ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: software-properties-gtk 0.99.42 ProcVersionSignature: Ubuntu 6.6.0-14.14-generic 6.6.3 Uname: Linux 6.6.0-14-generic x86_64 ApportVersion: 2.27.0-0ubuntu6 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Thu Feb 15 10:07:43 2024 InstallationDate: Installed on 2024-02-15 (0 days ago) InstallationMedia: Ubuntu 24.04 LTS "Noble Numbat" - Daily amd64 (20240215) PackageArchitecture: all ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> SourcePackage: software-properties UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/2053228/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
