Public bug reported: Binary package hint: apt
The problem in apt I'm reporting can be triggered through "Muon updater". I originally reported the bug to KDE but the author of Muon suggested me reporting the problem here, as it was an apt problem. The following is the original bug report about Muon updater (https://bugs.kde.org/show_bug.cgi?id=265741): ---------------------------------------------------------------- Version: 0.2 (using KDE 4.6.0) OS: Linux Please bear with me as this is a rather difficult bug to explain and reproduce. The problem appears when there are pending updates after a repository refresh (apt-get update), those updates are not applied and, later, Muon updater is opened (it will show the updated packages), the repositories are updated again and a newer version of one of the pending packages is found. My personal theory is that Muon updater still tries to mark the old packages which are now not present in the repositories, as a newer version of them was released. Anyway, I don't know Muon internals, so I could be completely wrong. Reproducible: Always Steps to Reproduce: 1. Add a frequently update repository to "Software sources" (for example, Chromium Daily PPA, https://launchpad.net/~chromium-daily/+archive/ppa). 2. Reload the repositories (apt-get update). 3. Hopefully, there will be pending updates. Muon will report them. 4. Don't reload the repositories until there are newer version of those packages (Chromium Daily should publish new packages every day). 5. Without reloading, open Muon updater. It will show the same old pending updates. 6. Refresh the repositories from Muon updater (Check for Updates). Actual Results: Muon updater will show an error dialog (the following is an approximate translation from the Spanish version): "The package system couldn't be started. Your configuration may be defective. Details: A file for package $PACKAGE couldn't be located. This could mean that you will have to manually fix that package." ("El sistema de paquetes no se ha podido iniciar. Su configuración puede estar defectuosa. Detalles: No se pudo localizar un archivo para el paquete $PACKAGE. Esto puede significar que necesita arreglar manualmente este paquete.") Expected Results: Muon updater should have suggested the newer version of the package as an update candidate without showing an error message as the update can be performed the next time Muon is opened. OS: Linux (x86_64) release 2.6.35-25-generic Compiler: cc ---------------------------------------------------------------- The following is the replly of the author of Muon (https://bugs.kde.org/show_bug.cgi?id=265741#c1): This is an issue with APT itself not being able to open the package cache. I would recommend reporting this bug at Launchpad: https://bugs.launchpad.net/ubuntu/+source/apt/ ** Affects: apt (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716599 Title: apt can't open package cache under certain circumstances -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
