Description Willi Richert 2011-10-21 09:09:33 UTC

Version:           0.2 (using KDE 4.7.2) 
OS:                Linux

I ran aptitude in parallel, which resulted in a locking problem with muon.
I removed the lock files and aptitude runs fine now. Muon still does not install anything (it used to work fine before I used aptitude in parallel).

I would like to have a menu item like "remove stale locks" or similar.

Reproducible: Didn't try

Steps to Reproduce:
-

Actual Results:  
Muon is stalled (probably due to locking)

Expected Results:  
Installing the programs

OS: Linux (i686) release 3.0.0-12-generic
Compiler: gcc

This is actually a bug, where on subsequent attempts to install an application after closing another app with a lock doesn't work, but hangs there. (For example, you are able to install things just fine when using the Muon Package Manager instead of the Muon Software Center.)

I suspect the failed, stale transaction is lying around preventing new transactions from running.

Cancel transactions that have failed from any error (other than cancel errors) rather
than just cancelling transactions when encountering AuthError.

This fixes issues with the Muon Software Center hanging on a certain transaction after
having any error other than an AuthError (such as a LockError, or CommitError, or...)
