Upgrade to 26.7 fails, no signature found

[SchengFui]

Hi there,

when trying to upgrade to 26.7 via console, this fails:

Minor updates may be available, answer 'y' to run them instead.
Proceed with this action? [26.7/y/N]: 26.7
Fetching packages-26.7-amd64.tar: ..[] failed, no signature found
*** OPNsenseWIN7.localdomain: OPNsense 26.1.11_10 (amd64) ***

Trying different mirrors does not help.

I'm a bit lost at this point, any ideas?

Thank you.

What's the full output when you press y instead of 26.7 ?
