Comment 3 for bug 1750600

Hello,
thank your for your answer.

With this new information, I was able to narrow down the problem. Now I think it's not a bug in Landcape.

I searched the USN database https://usn.ubuntu.com/usn-db/database-all.json for these updates. I found some packages which are released by the security repo but has no entry in the USN-database.

Example: I installed linux-firmware_1.157.15 and can update to linux-firmware_1.157.16 via xenial-security, but there is no entry for linux-firmware_1.157.16 in the database.

Is it possible that not every update in $release-security as an entry in the USN-database?

Best regards,
Norbert Härig
