plasma-discover stalled

Asked by Rock Ouimet on 2021-02-05

Since about a month plasma-discover, RStudio, and a java script (cafetran) do no longer launch. Here is the report for plasma-discover. The "segment fault" always shows.
What is the problem?
Thanks,
R

Hi,
Is it because de PPA for Lubuntu is problematic? See:

You'll need to report this either to the maintainer of whatever PPA you're getting plasma-discover from, or to Ubuntu if you're getting plasma-discover directly from the primary Ubuntu archive. Launchpad itself just provides the hosting, and Launchpad staff can't help you with this sort of thing.

Can you help with this problem?

Provide an answer of your own, or ask Rock Ouimet for more information if necessary.
