Attention All: InfluxData is rotating its Linux packaging signing key. Please see Linux Package Signing Key Rotation | InfluxData for more information.
Thanks for the notification, I was just updating systems running influxdb and apt returned the following:
E: The repository 'https://repos.influxdata.com/debian stable Release' no longer has a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Queue mild panic, then I found your post & the linked article, unfortunately the https://repos.influxdata.com/ URI is returning a “404 Not Found” so I cannot rotate the keys as per your guide at the moment.
It might be a good idea to pin your above post in the forums so that others can find it & the linked key-rotation guide more easily. 
Fyi, now that everything has been signed with the new key since January and nothing should be using the old key, we have revoked the old signing key (ie, https://repos.influxdata.com/influxdb.key (05CE 1508 5FC0 9D18 E99E FB22 684A 14CF 2582 E0C5)) and updated the keyservers. We’re in the process of updating https://repos.influxdata.com/influxdb.key now to contain the updated revoked key.
No changes have been made to the current signing key and since the old key hasn’t been used for signing for many months, this change should go unnoticed.
This is now done.
