Hey guys, I’m trying to install ignition on a VM with Linux (Ubuntu (24.04.3 LTS)). Installing the gateway (version 8.1.50) was pretty straightforward with no issues. The issues came when I tried to install the designer. I went to the gateway downloaded designer launcher and it came in a .tar.gz file (which I thought it would come some .exe or .run,) I extracted the downloaded folder and then had to run the designerlauncher.sh file inside the designerlauncher/app/ directory. It opened the launcher, I choose the gateway, and then when I select it to open the designer, the following popup shows:

Any guesses on what is happening? Can you help me out?  
I want to warn you that I’m a newbie in linux and still don’t much of my around it

I have had this issue before as well.  
This thread has some possible solutions: [Unable to start Designer or Client ERROR “This Launch Jar Signature is invalid. Contact an administrator”](https://forum.inductiveautomation.com/t/unable-to-start-designer-or-client-error-this-launch-jar-signature-is-invalid-contact-an-administrator/96092)

Okay, had to swim through other topics but I got it done with the topic that you provided. For any other users trying out to install the launcher:  
My issue was that the Designer Launcher didn’t create the configuration folder (`~/.ignition/designerlauncher-data`) when extracted from the `.tar.gz` file.  
It didn’t create that folder or the `designerlauncher.json` file, so the launcher couldn’t save settings or the signature verification cache — which caused the “This launch JAR signature is invalid” error.

The solutioon was to  
extract the .tar.gz under my user directory (`~/designerlauncher`)  
Manually create the folder  
`mkdir -p ~/.ignition/designerlauncher-data`  
Create the file  
`~/.ignition/designerlauncher-data/designerlauncher.json`

with the following content inside of it  
`{"signature.verification.strength": "AIR_GAPPED"}`

and after this designer launcher opened normally and was generating designerlauncher.log and allowing to conect to gateway without error
