This lab uses the same apache-tomcat-8.5.53.tar.gz file used in the Webserver Labs Apache Tomcat 01 class in another of my posts to this forum. The file no longer exists because apache have removed it. I used the same trick of downloading the apache-tomcat-8.5.54.tar.gz file, unpacking it and then renaming the directory back to 8.5.53 and then managed to complete the lab… this lab also needs fixing.
Thanks for reporting. We will fix it.
