I wanted to reinstall java which was accidently deleted, using this post.
As mentioned in the above post on runningsudo apt install default-jre, I got this error:
Reading package lists... Done

Reading state information... Done
default-jre is already the newest version (2:1.11-68ubuntu1~18.04.1).
0 upgraded, 0 newly installed, 0 to remove and 149 not upgraded.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

Setting up install-info (6.5.0.dfsg.1-2) ...

E: Sub-process /usr/bin/dpkg returned an error code (1)
The result of java --version is:
Command 'java' not found, but can be installed with:
sudo apt install default-jre
sudo apt install openjdk-11-jre-headless
sudo apt install openjdk-8-jre-headless
The result of apt list --installed | egrep 'jdk|jre' is:

As mentioned in the post tried this to fix the error:
sudo apt install --reinstall default-jre default-jdk default-jre-headless default-jdk-headless openjdk-11-jdk openjdk-11-jdk-headless openjdk-11-jre openjdk-11-jre-headless openjdk-8-jdk openjdk-8-jdk-headless openjdk-8-jre openjdk-8-jre-headless
But, it gave the same error.
The result of echo $JAVA_HOME is:
/usr/lib/jvm/java-11-openjdk-amd64/bin
The result of echo $PATH is:
/home/.local/bin:/home/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/bin:/usr/lib/jvm/jdk1.7.0/bin:/home/bin:/usr/lib/jvm/jdk1.7.0/bin:/usr/lib/jvm/java-11-openjdk-amd64/bin
I found that these links are broken,
usr/share/man/man1/jar.1.gz
usr/share/man/man1/jarsigner.1.gz
usr/share/man/man1/java.1.gz
usr/share/man/man1/javac.1.gz
usr/share/man/man1/javadoc.1.gz
usr/share/man/man1/javah.1.gz
usr/share/man/man1/javap.1.gz
When tried to open these file from the interface, got a warning message that these links cannot be used as it's alternatives does not exists in "/etc/alternatives/ "
The result of /usr/share/man/man1# update-alternatives --config java as a root user is:
update-alternatives: warning: alternative /usr/lib/jvm/java-11-openjdk-amd64/bin/java (part of link group java) doesn't exist; removing from list of alternatives
update-alternatives: warning: alternative /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java (part of link group java) doesn't exist; removing from list of alternatives
update-alternatives: warning: /etc/alternatives/java is dangling; it will be updated with best choice
There is no program which provides java.
Nothing to configure.
Looking at the inconvenience in reinstalling java as it seems it's not fully installed or removed, tried to completely uninstall java using this post.
As mentioned in this post, ran the following command:
dpkg-query -W -f='${binary:Package}\n' | grep -E -e '^(ia32-)?(sun|oracle)-java' -e '^openjdk-' -e '^icedtea' -e '^(default|gcj)-j(re|dk)' -e '^gcj-(.*)-j(re|dk)' -e '^java-common' | xargs sudo apt-get -y remove
But even this didn't worked giving out the same error while processing.
