It happens with Muon Updater and Muon Package Manager. Versions 1.4.1 and 1.3.1. I have to upgrade the package (flashplugin-installer) using Konsole, because with Muon never works fine. P.S: I installed flashplugin for the first time installing the package kubuntu-restricted-extras. Reproducible: Always Steps to Reproduce: 1. There's an update avaliable for flash plugin. 2. Upgrade it using Muon. 3. Flash doesn't work. Actual Results: Flash doesn't work after upgrading it with Muon. Expected Results: Flash works after upgrading it with Muon.
This is a packaging issue with the flash package. I'd recommend using the more robust "adobe-flashplugin" package from the Canonical commercial Parnter repository, which does not suffer from this issue.
It works fine with the terminal and using other package managers, but well...
Yes, it does fail within Muon, but the ultimate failure is an uncaught exception in the script the packaging runs to download the actual flash plugin. The difference would be that package managers like apt-get and Synaptic run dpkg in a terminal emulator, whereas package managers like Muon and PackageKit run dpkg in a pty. (A perfectly valid thing to do.) The script within the flashplugin-installer package erroneously assumes that the package is being installed in a virtual terminal emulator environment, which triggers the uncaught exception within the script. The adobe-flashplugin package, on the other hand, contains the actual plugin itself and doesn't rely on a post-installation script to fetch the plugin from adobe's servers, so it doesn't suffer the same bug.
Ok, thank you. I reported this bug in Ubuntu's Launchpad. I think it's more handier not having to add another repository to have Flash working without this issue, so I hope they can solve it.
