Cannot update on EC2 instance

[jgwhite0111]

It seems there is some issue with a PGP signature or corrupt package when running sudo ubos-admin update -v from a fresh EC2 image configured as per instruction.

This is covered in the FAQ: https://ubos.net/docs/administrators/faq-howto-troubleshooting/error-corrupted-package/

P.S. this "Undefined subroutine &UBOS::Utils::ageOfFileInSeconds called at /usr/share/perl5/vendor_perl/UBOS/Host.pm line 556." should not be happening. How old is this instance, and how long since the last update?
