After checking all the B-fips jobs, I found this issue only exist in amd64 nodes, in which they will try to access archive.ubuntu.com: Err:1 http://archive.ubuntu.com/ubuntu bionic InRelease Unknown error executing apt-key
But for s390x KVM, it will use ports.ubuntu.com: Hit:2 http://ports.ubuntu.com/ubuntu-ports bionic InRelease Probably something to do with the archive server? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1863092 Title: Testing node with B-FIPS will complain "Unknown error executing apt- key" Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Bug description: B-FIPS testing node will complain about "Unknown error executing apt- key" when running the apt update command.
