Autoinstall Config Failed

Hi,
I Tryed to write some Autoinstall config, but it seems to get an errror.
This is the code i used(only changed files):

AUTO_SETUP_INSTALL_SOFTWARE_ID=24    #will install MATE
AUTO_SETUP_INSTALL_SOFTWARE_ID=113    #will install CHROME

AUTO_SETUP_INSTALL_SOFTWARE_ID=16   #will install Buildessenz
AUTO_SETUP_INSTALL_SOFTWARE_ID=0   #will install Open SSH
AUTO_SETUP_INSTALL_SOFTWARE_ID=105 #openssh server

Thanks for your report.

Are you able to install the python3 package manuall?
apt install python3

Perhaps some temporary repo issue.
