Error after finishing the magento install 2.4.3-p1

[benjamin_boursault]

Hello there,

I've just resolved an error from the install of magento and then i succeeded to finish it.

After that i tried to boot on the initialisation page with the browser but i got an error like this : 

Not Found
The requested URL was not found on this server.

Apache/2.4.41 (Ubuntu) Server at xx.xxx.xxx.xx Port 80

so i search on google to solve this error and i've seen many people who got the same error and they said it was a bug from this version of magento 

so they said it should boot on the index.php who is normally at the root of the /magento directory on the previous versions

but on this version, it's in the /pub directory so i just booted on this directory with my browser but i got this error now 

An error has happened during application run. See exception log for details.

can somemone help me on that ?

Thanks for your future return

I think i've already tried solely the first command but i've ran it again anyway and then i ran the second and the third command and then i got this on my browser when i boot on "/magento/pub" :
