"true0s-update upgrade" ran fine and appeared to update hundreds of packages. However at the very end gave the following error:

Installing: GhostBSD-acct
pkg-static: Repository GhostBSD load error: access repo file(/var/db/trueos-update/pkgdb/repo-GhostBSD.sqlite) failed: No such file or directory
pkg-static: Repository GhostBSD cannot be opened. 'pkg update' required
pkg-static: No packages available to install matching 'GhostBSD-acct' have been found in the repositories
FAILED: Installing world base package: GhostBSD-acct

Has anyone else run into this? Any clues?

I am running GhostBSD 19.04.

Thanks.

Do not use, trueos-update or freenbsd-update, GhostBSD is not using TrueOS tools, we build GhostBSD from TrueOS that it.

Thanks. Good to know. Maybe the command trueos-update should be removed or renamed to /usr/sbin/trueos-update-deprecated ?

Actually, in the next release, it will be.
