Thank you for taking the time to report this bug and helping to make Ubuntu better.

The mirror in use (http://ftp.ntou.edu.tw/ubuntu) does NOT provide support for 22.04/jammy - thus you should change to using the main archive, or another found on https://launchpad.net/ubuntu/+archivemirrors

Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

I've marked this bug report as 'incomplete' as I've suggested a change, or using support methods, as I don't see this as a bug in the report code, but a consequence of using a mirror that doesn't provide support for 22.04 LTS. If you believe I'm in error, please leave a comment outlining why, and the status can be returned to "New".
