SUMMARY Package download progress bar does not display the actual progress and instead hangs at 0% for the duration of package download and jumps to 100% when download is complete. STEPS TO REPRODUCE 1. Mark a package for installation or upgrade. Preferably a large one, that would take time to download. For example, firefox-dbg (>400 MiB). 2. Click Apply Changes and watch the download progress bar against the package name. OBSERVED RESULT The progress bar hangs at 0% for the duration of the download (you can monitor the download by external tools for network activity monitoring), then jumps to 100% and the process continues to the next package or package installation. EXPECTED RESULT The progress bar should reflect the actual downloading progress. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.16.5 KDE Frameworks Version: 5.62.0 Qt Version: 5.12.4
I can add that the progress bar updates if the window with the list of packages being downloaded needs to be redrawn. For example, when I hover mouse over the line with the package being downloaded or switch focus to another window and back.
