I have two FreeBSD 12.0-RELEASE systems exhibiting the same problem when attempting to update to the latest patchlevel using freebsd-update.
# freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 3 mirrors found.
Fetching metadata signature for 12.0-RELEASE from update4.freebsd.org... done.
Fetching metadata index... done.
The update metadata is correctly signed, but
failed an integrity check.
Cowardly refusing to proceed any further.
Not sure how to proceed.
Should be fixed now.
Confirmed, it's working fine on both machines now. Thanks!
I am trying to update an old FreeBSD 10.3-RELEASE (on a cloud vps) to 12.0-RELEASE but I get the message in the bug description. Same if I try with 11.2-RELEASE.
Is there something wrong again or is my system too old to update? Is there anything I can do?
(In reply to Lorenzo Salvadore from comment #3)
This is an unrelated issue. Update to the last release from your current stable branch first; sometimes there are upgrade issues which we need to fix via Errata Notices, but those only go out for supported releases.
