SUMMARY
THis problem appeared when you use the commanda pkcon refresh and pkcon update in any terminal. Maybe is a problem related to the commands and i don't know if this bug is in the correct section because i don't know where place it.

With pkcon refresh, shows some ppa's you have added, but sometimes, the command shows some extra packages, that end like: Metadata, Icons, DEP-11 Metadata, etc.

Pkcon Update shows some errores while the update process related to QTCommandLineParser or org.kde.debconf: DEBCONF----> "O OK"

I've never seen this type of errors, so i don't know if its a bug, or is more simple to solve.

Finally, this errors apeared like 2 months, i was sure that maybe the problem was in my installation, but even reinstalling everything, the problem reappeared so I think it's a bug


STEPS TO REPRODUCE
1. Run pkcon refresh or pkcon update command in any terminal

OBSERVED RESULT
what I explain above


EXPECTED RESULT
