Error when installing easyTravel on Ubuntu 20 Linux

[joseph_pham]

Hi. I keep getting install error with /java/util/jar/Pack200 when installing Dynatrace on Ubuntu 20 Linux. Getting this error (but not in Linux Mint) while installing the easyTravel demo package with java -jar dynatrace-easytravel-linux-x86_64.jar command. Any ideas?

Which JVM are you using? You might be using a newer version, since it was removed in Java 14:

If this is not the case, can you give a more detailed error?

yes it's Java 14 I am using. So I need to remove Java 14 and go with 11?

I had to remove version 14, install version 11 and 8 jdk and java -jar command finished successfully. Thanks for your help Antonio.
