Get 64-bit version Ubuntu 18.04 from Ubuntu 18.04 releases and create bootable USB Stick (SD-card does not work, as the BIOS of Intel does not support booting from SD-Card).

Follow install instructions:

• Use English as language but German keyboard settings
• Skip wifi settings (setup eduroam later)
• Choose minimal installation
• Choose "erase disk and install Ubuntu" (clean install)
• Select Munich as location
• Select SSD (256GB ATA SanDisk)
• Choose username: "exploration"
• Choose computername: "rover"

Update system by typing sudo apt update, sudo apt upgrade and sudo apt dist-upgrade

To enable ssh connections, install openssh: sudo apt install openssh-server

Enable the ssh service by typing sudo systemctl enable ssh

Start the ssh service by typing sudo systemctl start ssh

Create a .pem file with the certificate from the warr wiki in it. (currently /home/exploration/eduroam_cert.pem)

official Ubuntu help page add the file /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE

network={
  ssid="eduroam"
  key_mgmt=WPA-EAP
  pairwise=CCMP
  group=CCMP TKIP
  eap=PEAP
  ca_cert="path/to/certificate.pem"
  identity="xxXXxxx@eduroam.mwn.de"
  domain_suffix_match="radius.lrz.de"
  phase2="auth=MSCHAPV2"
  password=hash:YYYYYYYYYYYYYYYYYYYYY
  anonymous_identity="[email protected]"
}

replace the X with the lrz username and the Y with the hash of the password. You can look up those information on our private warr wiki. ATTENTION: the path has to be absolute (/home/exploration/... instead of ~/...)

add following lines to the file /etc/network/interfaces

auto wlp58s0
iface wlp58s0 inet dhcp
        wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

reboot
