Hi, Surely it might be region specific or temporary issue.
According to Debian mirror status [1], mirrors.xtom.jp was timed-out at that time, but it was resolved now. I've tried again and this issue is still reproducible even though mirror status was resolved. [1] https://mirror-master.debian.org/status/mirror-status.html I've collected syslog. If the problem was reproduced, it takes 20 or 30 minites to be processed. It seems that choose-mirror causes this edge case.
