I never installed Kasm, so I don’t know how it is installed and how it installs Docker, but if Kasm downloads incompatible compose or tries to access the daemon API using an old, outdated api client from code, it is something that Kasm developers have to fix.. As a workaround, temporarily you can try what @meyay recommended here
As you can see, there were other software as well that didn’t update the client library in time.
