[Jaunty] PackageKit is broken: "Launch helper exited with unknown return code 1"

[Dmitry Tantsur]

Binary package hint: packagekit

Jaunty with all latest updates, PK 0.3.14-0ubuntu4
How to reproduce:
 In fact run any application from packagekit-gnome, example:
- Run gpk-update-viewer
- You'll see an error message about "Unexpected internal error"
- Click "Details". you'll see "Launch helper exited with unknown return code 1"
- update-viewer window is shown but update list is always empty. Any attempt to update package list will lead to the same result as described below.

No information is written to console.

same error on kubuntu jaunty with kcmshell4 kpk_update

This would correctly be diagnosed as a backend error. The bug lies in the packagekit backend itself, not kpackagekit.

I confirm this bug on kpackagekit, maybe a packagekit bug.
It would be cool to have it sorted as it's rather unusable as it is.

When I run kpackagekit from a terminal I see the following:

 New transaction with tid "/28_aecddbce_data"
KPackageKit(4176) KpkIcons::actionIcon: action unrecognised: 12
enumFromString ( State ) : converted "" to "" , enum value -1
KPackageKit(4176) KpkTransaction::errorCode: errorCode: 3 "Launch helper exited with unknown return code 1"
KPackageKit(4176) KpkTransaction::finished: Failed.
KPackageKit(4176) KpkTransaction::finished: Yep, we failed.
removing transaction from pool : "/28_aecddbce_data"

Shouldn't this bug be marked as a security issue? KDE users cannot get security updates without dropping to a shell...

Hello Guys,

i have the same problem like you.
When i start it from the Terminal, i got this output:

enumFromString ( Group ) : converted "unknown" to "Unknown" , enum value -1
user@tux:~$ New transaction with tid "/41_adbedcab_data"
New transaction with tid "/42_bcbabcce_data"
removing transaction from pool : "/41_adbedcab_data"
removing transaction from pool : "/42_bcbabcce_data"

When I run up-dating system I found Internal Error massage "Launch helper exited with unknown return code 1", both from gnome and kde.

Also, I got problem when checking via up-date manager, like this;
E: Problem executing script APT::Up-date::Post-invoke'/usr/bin/daptop--post'
E: Sub-process returned an error code

Is this still an issue in the final version of K/Ubuntu 9.10?

[Grosser (jensi05)]

Hello Jonathan Thomas,

This bug is not in the current Version 9.10.

Thanks for your question.

Greets.

Thanks for the update. This was one of the things that drove me back to gnome. :P
