Since tomcat has been installed by unpacking a tar.gz file to /opt/tomcat, the uninstall process will be to remove /opt/tomcat.

cd /opt
sudo rm -rf tomcat

I know this question has been asked a lot but I am facing some problems. When I upload a war file to tomcat I cant get to to start and i get this error
```
FAIL - Application at context path [/fuseki] could not be started
```
I then have tried to remove tomcat 9 so I can install tomcat 8 but I cant follow the instructions given on other threads because when I run
```
dpkg -l|grep tomcat 
```
returns nothing.
```
sudo apt-get remove tomcat
```
returns
```

  I followed these instructions linuxize.com/post/how-to-install-tomcat-9-on-ubuntu-18-04

  So basically, you downloaded a tar.gz archive and unpacked it to /opt/tomcat. So cd /opt and sudo rm -rf tomcat should 'uninstall' it.

  I did what you said but I hope it is the correct way and it purged everything and I can install tomcat 8 .
