Bug 443809

SUMMARY
Each time Discover is opened, "fetching updates" takes several minutes

STEPS TO REPRODUCE
1. Open Discover in KDE neon updated to Plasma 5.23 or in a clean install of KDE neon (Plasma 5.23)

OBSERVED RESULT
Fetching updates goes on and on for several minutes. Once it's eventually done, close Discover, reopen it and "fetching updates" goes on and on yet again.


EXPECTED RESULT
It should not take so long especially when Discover is opened immediately after just updating. 

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: KDE neon 
(available in About System)
KDE Plasma Version: 5.23.0
KDE Frameworks Version: 5.87
Qt Version: 5.15.3

ADDITIONAL INFORMATION
Using `pkcon refresh` followed by `pkcon update` is fast.

(BTW, both the VM and the bare metal install have been restarted after their installation.)
