After offline upgrading from Leap 15.1 plasma applet for software updates reports error:

Updating with zypper works fine. But, seems, zypper in first time reported this error too with more detailed message - in particular, that checksum for repos is changed.
How can I fix this problem?

The following command should clear your repo cache and allow it to be rebuilt

zypper clean --all

Thank you for reply.
I did:

sudo zypper clean --all

After:

sudo zypper refresh

Here zypper reported error for NVIDIA repository:

Repository ‘NVIDIA’ is invalid.
[NVIDIA|https://download.nvidia.com/opensuse/leap/15.2] Valid metadata not found at specified URL
History:

  • susedata.xml.gz has wrong checksum
  • Can’t provide ./repodata/susedata.xml.gz

I’ve deleted NVIDIA repo, and now the plasma applet works correctly!
