i tried to install java using the following :
apt install default-jre
but when i want to see the version using :
java -version
it says :
apt install default-jre # version 2:1.11-72, or
apt install openjdk-11-jre-headless # version 11.0.8+10-0ubuntu1~20.04
apt install openjdk-8-jre-headless # version 8u265-b01-0ubuntu2~20.04
apt install openjdk-13-jre-headless # version 13.0.3+3-1ubuntu2
apt install openjdk-14-jre-headless # version 14.0.1+7-1ubuntu1
i run the installation command again it again :
Reading package lists... Done
Building dependency tree
Reading state information... Done
default-jre is already the newest version (2:1.11-72).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
and when i try to run the following :
sudo update-alternatives --config java
i got this :
There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-11-openjdk-amd64/bin/java
Nothing to configure.
update-alternatives: warning: forcing reinstallation of alternative /usr/lib/jvm/java-11-openjdk-amd64/bin/java because link group java is broken
update-alternatives: warning: not replacing /usr/bin/java with a link
and the same keep happening over and over .
i had no problems during installation and all ok when i run a program that depend on java or run the java -version it is not working .
regards
