Can't download themes or emulators error 'tar -xv -z -C

No it doesn't I think... This is what it shows ...!

@edgarsv It looks like either your date/time is off (which kind of is, based on your first screenshot) or your installation is too old and it's missing the necessary CA info to validate the HTTPS connection's certificate to github.com.

Try updating the ca-certificates package and make sure your date and time are correct. Run this from the command line or from an SSH session.

# update ca-certificates
sudo apt-get update
sudo apt-get -y install ca-certificates

# Check the date/time
date

Here is how it worked...

The only part I understood was that the date is wrong.

mitu

Try setting the date from the internet

sudo systemctl stop ntp
sudo ntpdate 2.debian.pool.ntp.org

# Check the date again
date

edgarsv

After first command nothing happened but after the 2nd command it said command not found

@edgarsv Try installing the ntpdate command with

sudo apt-get -y install ntpdate

and then retry to set the date.

edgarsv

I did what you told but the date didn't change saying 8 Jul 15:48:38 ntpdate[1531]: no server suitable for synchronization found

mitu

@edgarsv Try with the well known NIST time server:

sudo ntpdate time.nist.gov

edgarsv

That didn't work either... Is there a way to set by my self? What could the reason for it not founding the servers?

mitu

@edgarsv You can set the date with timedatectl - see https://wiki.archlinux.org/index.php/Time#Set_system_clock. But I suspect the problem is that your internet connection is not working correctly, RetroPie would have set the time and date automatically from the internet.

Probably easiest to just start with a 4.4 image - Jessie support will be dropped by us in the future anyway.

edgarsv

So... What should I do?

edgarsv

Should I change retropie's version to 4.4? or try to replase raspberry pi zero to raspberry pi 3?

edgarsv

Is that the solution for me?
