apt-get update shows warning

[nandersen]

According to hardening guide one should run two commands:

sudo apt-get update
sudo apt-get upgrade

The first command throws the following message:

W: The repository 'https://conversionupdates.paloaltonetworks.com expedition-updates/ Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Is this a problem, or can it be ignored?

It can be ignored. We are working to change the APT Repository and then change the keys to be stronger and sign the Relase file as well.
