Hi,
last July 18th we were informed by Databricks that Ubuntu version 20.04 (operating system: Ubuntu 20.04.4 LTS) was going to be the only certified and supported Ubuntu version for the 10.4 runtime cluster we use. We have been experiencing some issues with Databricks libraries that didn't work since than. Could that have been caused by the new Ubuntu version that was pushed by Databricks? We read in an article: Databricks reserves the right to completely remove a release version from the API at any time after support ends, without prior notice.
Could that be what happened in this case?
