perfSONAR User Q&A and Other Discussion

[Chris Wilkinson <>]

I am a new user experiencing difficulties installing perfsonar-toolkit on Debian 11 for the first time following https://docs.perfsonar.net/install_debian.html

I have added the repository and key successfully but the installation fails with messages about unmet dependencies.

openjdk and postgresql are not currently installed.

# sudo apt-get install perfsonar-toolkit

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:
