Can't Start VStar on my Ubuntu 20.04 Linux

Hello,

I am a new user. I don't understand how to start VStar within my Ubuntu 20.04 Linux disro.

Here is what I have done to date,

1. I downloaded the tar.gz file.

2. I untarred the file into my Applications folder.

3. Using the Command Line I cd to the Vstar Folder within the Applications folder.

4. I typed VStar.sh and hit return.

5. I got the error message VStar/sh command not found,

6. I checked my version of JAVA and I have the latest version but I also downloaded version jre 1.8 and installed it in /user/java/ but it doesn't show up when I use the command line and type java -version. What returns is the following:

openjdk version "14.0.2" 2020-07-14

OpenJDK Runtime Environment (build 14.0.2+12-Ubuntu-120.04)

OpenJDK 64-Bit Server VM (build 14.0.2+12-Ubuntu-120.04, mixed mode, sharing)

I read something about a blue button on the AAVSO webpage but I don't see such using the Firefox browser under Ubuntu 20.04.

So, I am at a loss now as to how to start the program. I did sign up for membership and logged in using my credentials.

Any help and/or pointers on what I need to do in order to start VStar will be most appreciated.\\

Thanks in advance for your advice!

John

uh Ha!

uh Ha!

You are not going to believe this but I figured out a way to run VStar on my dual boot HP Pavillion notebook computer running Ubuntu 20.04.

Sometimes, maybe lots of time one needs to think outside the box...

I had a similar issue with APT (Aperture Photometry Tool) and I requested help. What I got was the major builder for that software was a command line script. That script works great.

Can you figure out where I am going wih this yet?

So, knowing that both of these software packages run on java I altered that script by exchanging the APT.jar to vstar.jar:

java -Duser.language=en -Duser.region=US -Xmx4096M -jar APT.jar

java -Duser.language=en -Duser.region=US -Xmx4096M -jar vstar.jar

Then I cd to the VStar folder, cd to where the vstar.jar is and type in (copy and paste from a saved document file) the above command. BINGO!

VStar.sh

Hi John

Did you type:

VStar.sh

or

./VStar.sh

in the shell?
