Removing Java on ubuntu 22.04

Question

I tried the following command:

$java --version
openjdk 11.0.27 2025-04-15
OpenJDK Runtime Environment (build 11.0.27+6-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.27+6-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

hence I tried:

$sudo apt autoremove
[sudo] password for ********: 
Reading package lists... Done

The following packages will be REMOVED:
  chromium-codecs-ffmpeg-extra default-jdk-headless gstreamer1.0-vaapi gyp

Then I typed:

$apt remove default-jdk-headless

E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

$ rm openjdk-11-jre

rm: cannot remove 'openjdk-11-jre': No such file or directory zulfikar@lc2530:~$ rm openjdk-11-jre-headless rm: cannot remove 'openjdk-11-jre-headless': No such file or directory

I can't still remove Java because I am getting

$ java --version
openjdk 11.0.27 2025-04-15
OpenJDK Runtime Environment (build 11.0.27+6-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.27+6-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

Somebody please guide me.

Zulfi.

I found the following solution at : [[reddit.com/r/Ubuntu/comments/1kshg89/ubuntu_2204_removing_java][1]][1] (worked)

user@lc2530:~$ dpkg --get-selections | grep java

ca-certificates-java install gir1.2-javascriptcoregtk-4.0:amd64 install java-common install javascript-common deinstall libatk-wrapper-java install libatk-wrapper-java-jni:amd64 install libjavascriptcoregtk-4.0-18:amd64 install

user@lc2530:~$ sudo apt remove java-common
