Need help to install Dolibarr in Ubuntu 22.04

Ubuntu 22.04

Dolibarr 17.0.2-4_all.deb

After unsuccessful installing 17.0.1-4_all.deb version I am trying now to installing

version 17.0.2-4_all.deb.

First I have to explain this installation is stand alone not need to connect webserver.

After download all-deb and installed successfully when click to run the file a page open

with this error.

https://localhost/dolibarr

Unable to connect

An error occurred during a connection to localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer’s network connection.

If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

I don’t have enough knowledge to correct this if the cause is firewall or Firefox or anything

else how to correct this. Please help need this application to work properly

Thank you
