[Bug 1709699] Re: gpk-update-viewer fails with "Spawn of helper 'usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py' failed ... (No such file or directory)"

[Niklas Sombert]

I think this is really a bug in packagekit. On 18.04 I can also trigger
this by just running pkcon get-distro-upgrades in a terminal:

Transaction:    Getting upgrades
Status:         Waiting in queue
Status:         Starting
Status:         Finished
Results:
Fatal error: Spawn of helper '/usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py' failed: failed to spawn /usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py: Failed to execute child process ?/usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py?

The problem seems to be that in debian/rules this file is being deleted:

  58   │     # Ubuntu-specific, broken
  59   │     rm -f $(INSTALLDIR)/usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py


But it is still referenced in backends/aptcc/pk-backend-aptcc.cpp:

 287   │ /**
 288   │  * pk_backend_get_distro_upgrades:
 289   │  */
 290   │ void pk_backend_get_distro_upgrades(PkBackend *backend, PkBackendJob *job)
 291   │ {
 292   │     pk_backend_spawn_helper(spawn, job, "get-distro-upgrade.py", "get-distro-upgrades", NULL);
 293   │ }

Newer upstream versions of PackageKit (1.1.13) seem to have this file
removed - and also the reference in backends/aptcc/pk-backend-aptcc.cpp.
