Since yesterday, when I try to update those two recommended items, the process fails and the updates are still showing. Sometimes, but not always, AppCenter crashes and closes.
All other updates are working fine, I am on Hera 5.1, Dell XPS 9550.
Anyone else and/or ideas?
Thank you.
EDIT
After having tried the latest answer with no luck, I tried this:

No luck either though.
At this point, if no one else if affected by this and there is no solution, I hope that the next time those packages will be updated, it will automatically work. Hopefully? Maybe? :)
