Unable to install Jenkins on Ubuntu 18.04 due to Java incompatibility
I installed java default packages in Ubuntu 18.04 and tried to install Jenkins. When this did not work I searched for reasons for this and found that Jenkins needs Java 8 and the default Java in Ubuntu 18.04 is Java 10.
So, I removed all the files of Java from /usr/lib/jre folder and tried to install Java 8. It says they are already installed without downloading packages and when I tried to verify the version it said JAVA NOT FOUND.
How could I solve this issue?

It is a very bad idea to try to remove software installed by package managers by deleting files. Maybe you're new to Linux and don't realise that software components are distributed to various location in the system, that packages depend on each other and that a database of what is installed is meticulously maintained by the package management system. If this database is corrupted by you making its info wrong by deleting stuff, sooner or later your system will be FUBAR and you will have great trouble figuring out how to fix it. I strongly suggest you learn to use package managers like APT.

I had the same issue.
Info in repositories is not right.
If you follow logs you'll find the version you're installing is an archive. For me it was u191 today: 2019/01/16 but on website it's u201 or u202.
you have to change your repo info like this:
cd /var/lib/dpkg/info
sudo sed -i 's|JAVA_VERSION=8u191|JAVA_VERSION=8u201|' oracle-java8-installer.*
sudo sed -i 's|PARTNER_URL=http://download.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/|PARTNER_URL=https://download.oracle.com/otn-pub/java/jdk/8u201-b09/42970487e3af4f5aa5bca3f542482c60/|' oracle-java8-installer.*

Why to install and make it complicated?
Instead of installing Jenkins using package manager sudo apt install, a better option is run Jenkins as war.
- Download the latest stable Jenkins WAR file to an appropriate
directory on your machine. - Open up a terminal/command prompt window to the download directory.
- Run the command
java -jar jenkins.war. - Browse to http://localhost:8080 and wait until the Unlock Jenkins page appears.
By default Jenkins runs on port 8080, change port using java -jar jenkins.war --httpPort=9090
To keep jenkins running on Ubuntu even after terminal is closed, use
nohup java -jar jenkins.war --httpPort=9090 &

It is a very bad idea to try to remove software installed by package managers by deleting files. Maybe you're new to Linux and don't realise that software components are distributed to various location in the system, that packages depend on each other and that a database of what is installed is meticulously maintained by the package management system. If this database is corrupted by you making its info wrong by deleting stuff, sooner or later your system will be FUBAR and you will have great trouble figuring out how to fix it. I strongly suggest you learn to use package managers like APT.
