Help to install Dolibarr in Ubuntu 20.04

Ubuntu 20.04
Dolibarr 17.0.1-4_all.deb

I download this file and extract to folder then following installation instructions
“Then you can call page http://localhost/dolibarr and follow wizard steps.”
I get an error (404 Not Found The requested URL was not found on this server)
Can any one help on this.
Thank you.

Hello,

You do not need to extract but to install it.

  1. How to Install LAMP Server on Ubuntu 20.04? - Magefan
  2. dpkg -i Dolibarr 17.0.1-4_all.deb

After download the .deb file I click on it and surprisingly it open to extract which I did.

To install this file I had to use this “Open with Other Application > Software Install”.

After click on Software Install a page open with following error.

Error: Dolibarr config file content seems to be not correctly defined.
Please run dolibarr setup by calling page /install.

Need help on where to find the dolibarr setup and the /install.
