[Solved by reboot] 26.7 Update-> "failed, signature invalid"

[Cableguy_]

Try another mirror

That led me into this in the first place (changing & testing mirrors via browser GUI). How to change mirrors in console, and which one should work?

If vi doesn't scare you you can edit /usr/local/etc/pkg/repos/OPNsense.conf and use pkg.opnsense.org

Changes there are not permanent but it should suffice to download the 3 files needed for the major upgrade.

Once you edited the file type exit and 12 to retry the 26.7 upgrade
