Repository signing key update for Kopano and Z-Push repositories !
The repository signing key for the Kopano repositories was updated on April 21, 2022, as it would have expired on April 29, 2022.
If you configured the usage of the Kopano / Z-Push repositories before April 21, 2022, the signing key must be updated locally on your Kopano server with the following command with root privileges:
curl https://download.kopano.io/zhub/z-push:/final/<distribution>/Release.key | apt-key add –
For example with Ubuntu 20.04:
curl https://download.kopano.io/zhub/z-push:/final/Ubuntu_20.04/Release.key | apt-key add –
The signing key can be accessed without subscription. The Supported Repositories use the same signing key, so that it can also be used for access there and does not have to be exchanged separately.
