Install debian 10 - buster on external HDD with USB adapter

dd if=debian-live-10.1.0-amd64-standard.iso of=/dev/sda bs=512k # write ISO file to USB pen drive (8GB)
boot the pen with UEFI support (Esc and F9 to access Boot menu on HP)
after boot change the layout to pt in the file /etc/default/keyboard and then run setupcon
Boot the pen again and choose Debian installer (console)
Select portuguese language and configure the locale accordingly
Use guided partinioning, whole disk, scsi5 , sdc with 500 GB
3 partitions were created, ESP, root / with ext4 and a swap partition
Don't use network mirrors
Define root password and add a user
Go through all the steps and reboot
Use the pen again to configure extra EFI definitions inside the ESP partition
Mount the ESP partition and inside the EFI folder create the BOOT folder
copy all files inside the debian folder to the BOOT folder
Go to the BOOT folder and copy the shimx64.efi to BOOTx64.efi
Boot using the HDD disk
If an error appears saying "/dev/sdX doesn't exist" with means grub didn't write the right HDD device name. It's required to acces grub options before boot and change the device name
After a proper boot is made into the HDD we need to run the command update-grub to update the grub with the right device name
To use WiFI we need the firmware-iwlwifi_20190114-2_all.deb to be installed, download it
Install using dpkg -i firmware-iwlwifi_20190114-2_all.deb
The WiFI device detected is wlp2s0
ip a; iwconfig; ip link set wlp2s0 up; iwlist scan
An conf file in /etc/wpa_supplicant/wpa_supplicant.conf is required

ap_scan=1
ctrl_interface=/var/run/wpa_supplicant
network={
  ssid="?????????"
  scan_ssid=1
  proto=RSN WPA
  key_mgmt=WPA-PSK
  group=CCMP TKIP
  pairwise=CCMP TKIP
  psk="???????"
}

Run command wpa_supplicant -B -c/etc/wpa_supplicant/wpa_supplicant.conf -i wlp2s0
Update the file /etc/apt/sources.list and comment cdrom entry

deb http://ftp.pt.debian.org/debian/ buster main contrib non-free
deb-src http://ftp.pt.debian.org/debian/ buster main contrib non-free

apt update
apt install xorg wmaker xterm lightdm firefox-esr alsa-tools alsa-tools-gui alsa-utils alsa-oss alsamixergui libalsaplayer0 htop wmclockmon vim openjdk-11-jdk docker.io
/sbin/usermod -a <user> -G docker
Test X using startx command
service lightdm start
Inside /etc/lightdm/lightdm.conf in [Seat:*] add display-setup-script=setxkbmap pt
To control the sound use the alsamixer command. The m key mutes and unmutes the master sound control
end the current session and start a new one to be able to use docker (docker ps)
