Seems like the file that is on the website is not a shell script but looks like an html file. I also downloaded the file using ftp and took a look at the file leading to my conclusion that it is not a bash script…
The installation fails with the following error (both with the sudo wget call as well as running the downloaded bash script) :
bash: line 1: syntax error near unexpected token `<'
bash: line 1: `<!DOCTYPE html><html lang="en" data-revision="1718182317766"><head><script async="" src="https://www.googletagmanager.com/gtag/js?id=G-E3QPKPNE8N"></script><script>window.dataLayer = window.dataLayer || [];'
