Summary

Everything goes on well except 'Update' in Ubuntu Software:

Unable to get list of updates: Failed to update metadata for lvfs: checksum failure: failed to verify data, expected ab367e987025d2339a62fb40a400149f7dc7dc7def5

Process

Since yesterday, I cannot use the 'update' function in Ubuntu Software anymore, I don't know the exact reason.

Current and expected result

I remember that there are 4 software still waiting for update yesterday, but they disappeared and the update module in Ubuntu Software is broken, I wish it can work well like before.

    I'm facing this error message as well (Discover 5.18.5 on Kubuntu 20.04.3), but it doesn't prevent me from installing package updates though.

Open terminal and try this command

From man page:

    That may or may not fix it. As of 2021-10-12, there's an open bug and they're still trying to pin down the root cause.

    The real answer is in @ssokolow s comment: this is a known bug in fwupd. According to the bug comments, the forced refresh workaround is only temporary, the error message will return in 24 hours. Ubuntu bug report on Launchpad: bugs.launchpad.net/ubuntu/+source/libjcat/+bug/1943833
