Short lived warnings during upgrading.
 

Hi All,
NAME="Ubuntu"
VERSION="20.04.4 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.4 LTS"
VERSION_ID="20.04"

'Discover' alerts me to updates, but I get a short lived message that I can't capture of copy, (I raised this some time ago in its own thread, no solutions yet though!).

The gist of the latest message is as shown below:

"Failed to update metadata for lvfs: checksum failure: failed to verify data, "

It then goes on to present a long hex number.

All help and comments appreciated

Regards

Chris
