Starting Out Need to Install Zoom & Java
« on: December 03, 2019, 11:39:28 pm »
Hello,

I've been reading articles on Forbes about a guy that has switched to Linux and who has a lot to say about Peppermint and what it does for the battery life on his laptop.

I'm looking at using Peppermint for the desktops my daughters use for their online school. I've installed Peppermint successfully, but for their school the need to install Zoom (video conferencing), and then their website appears to require the installation of Java in order to get into their collaboration tool.

Is this something that's doable, and if so, how difficult is it going to be for someone who is somewhat technical, but has no experience at all with Linux?

Thanks,

Dean

Hi WriterDean, and welcome to the forum :)

To install Zoom in Peppermint 10 (64bit) ...
(if you need instructions for Peppermint 10 32bit, just ask)

Open a terminal and run these commands in sequence:
Code: [Select]
sudo apt-get install libxcb-xtest0
then:
Code: [Select]
wget -O /tmp/zoom.deb https://zoom.us/client/latest/zoom_amd64.deb
then:
Code: [Select]
sudo apt-get install /tmp/zoom.deb
you should now find Zoom in the main menu at:-

Menu > Internet > Zoom

Thank you very much for your help! That worked perfectly for installing Zoom.

I've done some searching around the commands you instructed me to use. I understand that the first one installed a tool that gets files via http/https.

The second grabbed the file, and the third installed the file. How did you know that the zoom file was at that address?

I managed to install java. Then I did some reading around what was required to run .jnlp files, which led me to install iced tea. I also installed the icedtea-plugin in an effort to integrate the package with my web browser, but upon closer reading, it looks like that is no longer supported, so I'll have to uninstall that.

I successfully used javaws to have iced tea try and open up the .jnlp file, but it's complaining that the jnlp file is expecting java 1.6 and I've install java 11.

What is the best way to install java 1.6? Do I need to uninstall 11, or can I have both installed at the same time. I found some stuff that makes me think that I can have both, but thought it best to check while I'm asking about getting 1.6 installed.

Thanks again!

Looked here for the download link
https://zoom.us/download?os=linux
and here for a dependency list
https://support.zoom.us/hc/en-us/articles/204206269-Installing-Zoom-on-Linux#h_89c268b4-2a68-4e4c-882f-441e374b87cb



Which java runtime environment would you like to install .. the latest Oracle Java 13 ?

If so, open a terminal and run these commands in sequence
Code: [Select]
sudo add-apt-repository ppa:linuxuprising/java
then
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo apt-get install oracle-java13-installer
during the installation you will be prompted with a screen to accept the license .. hit the Tab key to highlight "OK" in red, then hit the Enter key to accept the license .. at the next screen hit the Tab key again to highlight "Yes" in red and hit the Enter key to accept .. java 13 should now continue to install.

Once installed. you can check your default java by running
Code: [Select]
java -version
and
Code: [Select]
javac -version
which should return
Code: [Select]
java version "13.0.1" 2019-10-15
Java(TM) SE Runtime Environment (build 13.0.1+9)
Java HotSpot(TM) 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)
and
Code: [Select]
javac 13.0.1
respectively.



to STOP Oracle java being the default java runtime
Code: [Select]
sudo apt-get remove oracle-java13-set-default
to make it the default again
Code: [Select]
sudo apt-get install oracle-java13-set-default



To UNINSTALL Oracle Java 13 completely:
Code: [Select]
sudo apt-get remove --purge oracle-java13-set-default oracle-java13-installer

Thank you!

I had already managed to install Java, but was still getting an error.

selected jre: /usr/lib/jvm/default-java
WARNING: package javax.jnlp not in java.desktop
Warning - your JRE - 11.0.4 - does not match requested JRE - 1.6
Warning - your JRE - 11.0.4 - does not match requested JRE - 1.6
Warning - your JRE - 11.0.4 - does not match requested JRE - 1.6
Warning - your JRE - 11.0.4 - does not match requested JRE - 1.6
selected jre: /usr/lib/jvm/default-java
Unrecognized option: -Xincgc
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I kept looking though, and managed to find this:

https://github.com/AdoptOpenJDK/icedtea-web/issues/205

I was chasing the wrong error. I opened up the .jnlp file, edited it to take out the reference to the deprecated argument and it's works. I've reached out to the vendor to try and get them to update their file, but can make due with the work around in the meantime.

Thank you again for all of your help. I'm sure I'll be back at some point posting another thread with more questions, but I'm good for now. :)
