freebsd-update(8) uses case-sensitive regexp to parse mirror list, which causes it to find no mirrors if ServerName capitalization is different from the one returned by host(1). This bug is also present in 9.3-RELEASE and possibly others. E.g.: ServerName is "update.FreeBSD.org" (default) `host -t srv host -t srv _http._tcp.update.FreeBSD.org' returns this: _http._tcp.update.freebsd.org has SRV record 1 40 80 update6.freebsd.org. _http._tcp.update.freebsd.org has SRV record 1 30 80 update2.freebsd.org. _http._tcp.update.freebsd.org has SRV record 1 35 80 update4.freebsd.org. _http._tcp.update.freebsd.org has SRV record 1 5 80 update3.freebsd.org. _http._tcp.update.freebsd.org has SRV record 1 50 80 update5.freebsd.org. freebsd-update uses sed(1) to parse this list: sed -nE "s/${MLIST} (has SRV record|server selection) //p" which returns nothing. It should look like this instead, because domain names are not case-sensitive: sed -nE "s/${MLIST} (has SRV record|server selection) //pi"
I'm also seeing this on 10.1-RELEASE. This is a duplicate of bug #170503
