[Samba] Ubuntu Focal Fossa 20.04 Samba 4.15.1 is online (amd64 only)

[L.P.H. van Belle]

Instruction are the same, but i'll post them anyway. 
Debian is being worked on currently so these are also coming soon. 
I do the 4.15.1 first due that anoying (fix now) bug. 
4.14.9 will be done later on. 

Enjoy. 

---------- THE REPO SETUP ---------------
Its a copy pastable what here below
I already adjusted it for you guys. 

#1) Choose http or https for you apt, both work, for https you need to :
apt-get install apt-transport-https gnupg

#2) Put the trusted (de-armored) key in /usr/share/keyrings/

wget -O- https://apt.van-belle.nl/louis-van-belle.gpg-key.asc |\
    gpg --dearmor | sudo tee /usr/share/keyrings/louis-van-belle.gpg > /dev/null

#3) (optional) setup a header line for the repo file.
echo "# AptVanBelle repo for samba." | sudo tee -a /etc/apt/sources.list.d/van-belle.list

#4) In the line below, change the OS and/or samba version to what you want.

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/louis-van-belle.gpg] http://apt.van-belle.nl/debian/ focal-samba415 main" \|
 sudo tee -a /etc/apt/sources.list.d/van-belle.list

#5) Optional: disable language translations, i dont use this on the repo.   
#If you add these, i have less messages in my webserver logs. ;-) THANKS! 

echo "Acquire::Languages { "none"; };" |sudo tee -a /etc/apt/apt.conf.d/99disable-translations


#You already installed samba 4.15.0?
apt update && apt upgrade -y

#You already installed samba 4.14. 
sed -i 's/414/415/g' /etc/apt/sources.list.d/van-belle.list
apt update && apt upgrade -y

#Clean install.

Yes, its for 18.04, but the instructions are the same. 

Few tips in general. 
- Please dont use DHCP IP's on server. 

- Make sure IP / hostname and domainnames are correct before you install. 

It just save's you from problems later on, changing can be done, but clean "correct" install,
