  • Obsolete garloff repositories will no longer be mirrored for Debian and Ubuntu
    (please see below on how to migrate to the Cloud OTC Tools repository)

How to enable the Cloud OTC Tools packages on Debian based systems

Cleanup home garloff

Older ECS installations may still have the home garloff repository configured.
Since this repository is obsolete and replaced by Cloud OTC Tools, it is strongly recommended to remove any remains of this repository from /etc/apt/sources.list and /etc/apt/sources.list.d/.

Configure repository URL

Please have a look at or our local mirror to find the correct URL for your distribution and version.
Hint: You can also use a command line browser like w3m to do this.

For example the repository URL for Debian 10 is

To configure the repository on your system create the file /etc/apt/sources.list.d/cloud-otc.list with the following contents (this example demonstrates Debian 10):

# otc-tools
deb [arch=amd64] /

Install the apt key

If you would run apt update now, you would get a error message like: "The repository ' Release' is not signed."
To fix this the apt key for the Cloud OTC Tools repository needs to be installed.

For this the apt cache needs to be updated ignoring the missing key:

$ apt -o Acquire::AllowInsecureRepositories=true update

Then the cloud-otc-keyring package can be installed:

$ apt install --allow-unauthenticated cloud-otc-keyring

Now you run apt update, again. It should not show any errors anymore. The repository is now ready and can be used to install and upgrade packages.
