Unlike Oracle Solaris with native ZFS, OmniOS stable is compatible with Open-ZFS but with its own dedicated software repositories per stable/lts release. This means that a simple 'pkg update' gives the newest state of the installed OmniOS release and not a newer release.
To update to a newer release, you must switch the publisher setting to the newer release.
A 'pkg update' initiates then a release update.
An update to 151050 stable is possible from 151046 LTS.
To update an earlier release, you must update in steps over the LTS versions.
Note that r151038 is now end-of-life. You should upgrade to r151046 then r151050 to stay on a supported track. r151046 is an LTS release with support until May 2026, and r151050 is a stable release with support until May 2025.
For anyone who tracks LTS releases, the previous LTS - r151038 - is now end-of-life. You should upgrade to r151046 for continued LTS support.
