Update alternatives ошибка нет альтернатив для java - Ремонт и установка крупной бытовой техники

I have Java 11 and 8 in my Ubuntu 18.04, side by side.
I mean to set Java 8 as the default.

What I get:

    $ sudo update-java-alternatives --set /usr/lib/jvm/java-1.8.0-openjdk-amd64
    update-alternatives: error: no alternatives for mozilla-javaplugin.so

    update-java-alternatives: plugin alternative does not exist: /usr/lib/jvm/java-8-openjdk-amd64/lib/IcedTeaPlugin.so

How can I get both plugins if they exist, work.

I am not sure if using (see this)

    sudo update-java-alternative —jre-headless -s java-1.8.0-openjdk-amd64

is ok, so I did not try it.
Could it break anything?
The Following are results after update-java-alternatives

    $ sudo update-alternatives --config java

I try to setup nativescript-vue on linux by following steps on nativescript website. when I use this command

sudo update-alternatives —config java

but have an error

update-alternatives: error: no alternatives for java

Please tell me how to fix this problem……

Try

sudo update-alternatives --install /usr/bin/java java  path_to_java 1

In my case the path was /usr/lib/jvm/java-8-openjdk-amd64

Do you have java installed?
Check if you do by running java -version in the command line/terminal

Хочу что бы JDK11 был выбран, по умолчанию, вручную. Ввожу команду:

 sudo update-java-alternatives --list

Мне выдает две версии 8 и 11

java-1.11.0-openjdk-amd64      1111       /usr/lib/jvm/java-1.11.0-openjdk-amd64
java-1.8.0-openjdk-amd64       1081       /usr/lib/jvm/java-1.8.0-openjdk-amd64

Далее выбираю java 11.

 sudo update-java-alternatives --set java-1.11.0-openjdk-amd64 --verbose

И начинают сыпаться ошибки.

Подозреваю нет альтернатив потому что этих компонентов просто нет в новой джаве, но тогда откуда они взялись?

The command update-java-alternatives -s jre-8-oracle-x64 is completely valid (found in documentation also here) but I get errors.
The package is also seen in the list of Java packages

Inside a Debian 10 VM I have first installed OpenJDK 11, and it was all OK.
Then I have installed Oracle JDK 13 according to instructions posted in Computing for geeks, that means wget-ting the .deb file and install it with dpkg -i.

I have got no errors, but when running update-alternatives --config java I get this answer:

There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-11-openjdk-amd64/bin/java

Why? How can I switch from one JDK to the other?

The alternatives are handled by pre- and post-install hooks. There seems to be no hook included in the package you downloaded, but you can easily add an alternative manually:

# update-alternatives --install /usr/bin/java java /path/to/OracleJDKs/java 2
# update-alternatives --install /usr/bin/javac javac /path/to/OracleJDKs/javac 2

Afterwards you should be able to select a Java version by running update-alternatives --config java and update-alternatives --config javac.

However, the java-package package always provided an easy way to install Oracle JDK on a Debian system. Since I have not used it for quiet a while I can not say if it is still compatible with current Java releases.

I’ve been trying this tutorial:
How To Manually Install Oracle Java on a Debian
to install Java on Debian 8, but I’m getting the following error :
update-alternatives: error: alternative path /opt/jdk/jdk1.8.0_05/bin/java doesn't exist

I checked the directory and observed that the directory actually exists. The output of the ls command is as follows:
-rwxr-xr-x 1 uucp 143 5730 Apr 10 13:53 java

I don’t know how to solve my problem and fix my Java installation. I’ve checked about what uucp actually means but have no idea why it’s there.

I need to get Oracle Java 8 installed.

You’d be far better off using the Debian java-package package to install Oracle Java. It allows you to build a Debian package file from the Oracle Java binaries, a package that can be managed using the regular Debian tools (including update-alternatives).

For Debian 8.x, the currently supported Java versions are (from here):

Oracle (http://www.oracle.com/technetwork/java/javase/downloads) :

The Java Development Kit (JDK), version 6, 7 and 8

The Java Runtime Environment (JRE), version 6, 7 and 8

The Java API Javadoc, version 6, 7 and 8

Basically:

Install java-package (apt-get install java-package).
Download (but don’t install) the Oracle Java package from the Oracle site.
Use make-jpkg to build a package from the Oracle Java installer you’ve downloaded.
Install the Debian package you built as part of step 3.

For more information, see here (currently slightly out of date) and the make-jpkg manual page.

Note: Make sure you remove the Oracle Java binaries you manually installed before installing the package you built with make-jpkg, otherwise you are sure to run into problems.

java-package is of course a better idea.

For now, your problem can be related to permissions.

chown <current_user>:<whichever_group> /opt/jdk/jdk1.8.0_05/bin/java where current_user is the user you want to run java with (can be root) and chmod -R 755 /opt/jdk/jdk1.8.0_05

And then try.
