Hi All,
I am trying to install the Nespicase+ safeshutdown script on Galisteo 128gb image rp3b

when I run the Wget command
wget -O - "https://raw.githubusercontent.com/RetroFlag/retroflag-picase/master/recalbox_install.sh" | bash

I get this error message

ERROR: cannot verify raw.githubusercontent.com's certificate, issued by 'CN=DigiCert SHA2 High Assurance Server CA,OU=www.digicert.com,O=DigiCert Inc,C=US':
Unable to locally verify the issuer's authority.
To connect to raw.githubusercontent.com insecurely, use `--no-check-certificate'.

when I run the command with no check certificate it does not work either.
any help would be sincerely appreciated.
