I just bought a Raspberry Pi 4 and want to install a web server on it.
I managed to install Apache and PHP, but I have issues with Mysql.
When I write the command "sudo apt install mariadb-server php-mysql", I get many error messages like "temporary failure in name resolution".
I cannot access any websites from the browser, and when I try commands like : "ping router" I get a "temporary failure in name resolution" message, with "ping 184.108.40.206" I get "From 192.168.1.54 icmp_seq=1 Destination Host Unreachable" ...
Do you have any idea about what's wrong and how I can solve this issue ?
Thanks for your time !
