Can't Start VStar on my Ubuntu 20.04 Linux

Tue, 11/10/2020 - 23:43

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!

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!

'No such file or directory'

Hello. I apologize for the replying in a 2 month old post. I also have the same situation like him/her. I was able to install the JRE 1.8 which is required to run the Vstar as I recently moved from 18.04 to 20.04 LTS.

When I tried run it via the command line ./Vstar.sh;

bash: ./Vstar.sh: No such file or directory

The java -version running is;

java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)

are there any resolve to this?

EDIT: I manage to pull it through haha.

"No such file or directory"

You say you are trying to launch VStar on the command line by entering "./Vstar.sh". You might try this: "./VStar.sh". Note the capital letter "S". VStar is the name of the executable script, not "Vstar".
