SUMMARY The discover notifier indicates "Updates available". I open Discover, and it indicates "Up to date", even after selecting "Refresh". This is the same bug as reported in numerous other bug reports that are indicated as being fixed (e.g., bug 438670). The bug is back with version 5.26.0 on Arch Linux (or at least on my Arch system). This bug does NOT occur on my Neon system, which also is updated to version 5.26.0. STEPS TO REPRODUCE 1. Log into the Plasma Desktop. 2. Look at the Discover Notifier, indicating "Updates available". 3. Open Discover, indicating "Up to date". OBSERVED RESULT The notifier indicates "Updates available", but Discover indicates "Up to date". EXPECTED RESULT The notifier would only indicate "Updates available" if actually there are updates available. SOFTWARE/OS VERSIONS OS: Arch Linux x86_64 Kernel: 6.0.1-arch1-1 (64-bit) Linux/KDE Plasma: KDE Plasma Version: 5.26.0 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 Graphics Platform: X11 ADDITIONAL INFORMATION There is another issue relating to Flatpaks which may or may not be related to this issue. I will file a separate bug report for that one. That issue is that when I opened Discover, it was hanging indefinitely on searching for updates. The work around for that was to rename /usr/lib/qt/plugins/discover/flatpak-backend.so to something else so that the file is not recognized by Discover. The problem with that solution, if my understanding is correct, is that Discover will not be able to find updates for Flatpaks.
I resolved this issue by performing the following: 1. sudo pacman -Rns flatpak 2. reboot 3. sudo pacman -S flatpak 4. flatpak update The other issue I reported, bug 460406, however, remains.
Cool, seems like you had an incomplete installation or upgrade.
