Public bug reported: Just ran `sudo apt-get update`, which is hanging indefinitely after the downloads complete, the last CLI output from which is:
Fetched 733 kB in 1s (399 kB/s) Looking at `top` suggests `appstreamcli` is the culprit as it's pegged at near 100% CPU usage: 100 0.1 18:29.02 appstreamcli If I kill the hung `sudo apt-get update` process with Control+C, the `appstreamcli` process goes away. Retrying `sudo apt-get update` has the same result. On a whim I also tried `sudo apt update`, but it seems to have the same problem. It hangs indefinitely and running it results in an `appstreamcli` process consuming 100% CPU.
