*** This bug has been marked as a duplicate of bug 325109 *** Actually not a duplicate as such (the reason I know that is because I just hit that crash mysefl :P)
While not obvious from the backtrace this crash is caused by
> void ApplicationUpdates::calculateUpdates()
not being able to resolve the package. The reason it cannot resolve it apparenlty is because ApplicationBackend doesn't refresh m_appList on reload.
How to reproduce:
- install a package foo
- m_appList now contains foo, but not bar
- package gets update that introduces dependency on completely new package bar
- a manual check for new updates is run via muon-updater
- the package cache for the updater now contains both the new foo and the completly new bar, m_appList still only contains foo
- resolution fails and assert fails
Created attachment 85093 [details] test archive to trigger the bug I am attaching a tarball with a simple test archive with two debs and a Packages list that allows the bug to be easily reproduced: - install kubuntu-docs - completely update system - extract tarball somewhere - edit sources.list and add the following with adjusted path as needed (mind the triple forward slash after file) > deb file:///home/me/bug330999 ./ - open muon-updater and use ctrl-r to refresh the crash - observe crash the tarball contains a fake kubuntu-docs package that depends on the other package (which is not present elsewhere thus not in the cache at startup), the cache refresh will pick up the new fake kubuntu-docs and try to resolve it's depdencies and fail the assert. (please note that for re-testing you need to delete the extracted directory, apt-get update, and extract it again to make sure the fake packages are gone from the cache) *** This bug has been marked as a duplicate of bug 325109 *** I can't reproduce the crash with muon-updater 2.2.0 Harald, can you check if it's fixed as Rohan suggested?
