We are running into same issue, looks like this PR will help fix it up. Can this be merged please?

We need to get those tests passing before we can merge it.

Fixed, all tests are passing now - I missed the RPM key name

@powersj I believe the $_baseurl values in the RedHat section also need updating?

(also removing the conditional for Amazon, if there isn't an Amazon-specific URL?)

$_baseurl = "https://repos.influxdata.com/${telegraf::repo_type}/\$basearch/main"

to be consistent with the RPM-based systems details at https://www.influxdata.com/blog/linux-package-signing-key-rotation/

[influxdata]
name = InfluxData Repository - Stable
baseurl = https://repos.influxdata.com/stable/\$basearch/main
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdata-archive_compat.key

I agree this should be done, but it is not required for the GPG key change that occurred today. I opened up #198 to track moving to the stable repos in a future change.
