> Application: plasma-discover (5.12.8)
I'm afraid version 5.12 is no longer supported. This was the old LTS version which has been succeeded by the newer LTS version of 5.18. Please upgrade to Plasma 5.18 (which is in Kubuntu 20.04) or Plasma 5.21 (which is Kubuntu 21.04).

I clicked in the «updates» button for install new packages and discorver was running, usually run slow, but i don't know if its normal, when Discover was «Searching for updates» the program chashed. That's all i know. :(
- Unusual behavior I noticed:

- Custom settings of the application:
