You need to make the shell scripts in Tomcat’s bin directory executable: $ sudo sh -c 'chmod +x /opt/tomcat/latest/bin/*.sh' The command below gives permission to the Tomcat user and group: $ sudo chown -R tomcat: /opt/tomcat When you get an update, all you’ll have to do is unpack your download and make the symbolic link point to it. $ sudo ln -s /opt/tomcat/apache-tomcat-9.0.45 /opt/tomcat/latest To ensure that you have more control over these updates, create a symbolic link called latest which points to the installation directory. Tomcat gets regular updates with security fixes and patches. $ sudo mv apache-tomcat-9.0.45 /opt/tomcat/ When the download is complete extract the archive to the /opt/tomcat directory: $ sudo mkdir /opt/tomcat They both achieve the same the same goal. NOTE: If you used wget, there's no need to use curl as well. Then use curl with the link you got from the Tomcat website: $ curl -O

First, download curl: $ sudo apt install curl If you have issues with using wget, you can optionally use the curl command to download Tomcat.

You can use the wget command to download the Tomcat zip file to the /tmp directory, a temporary folder location. The official binary distribution of Tomcat can be obtained from the Tomcat download page.
