Using oracle jdk8 works as well, though it involves a little bit of extra work, as it now requires login before allowing one to download it, as the license changed (personal use is fine though)
- go to: https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
- download the linux 64bit package
- unpack the downloaded file to a place of your chosing
- add the UNPACKED_PATH/jdk1.8.0_221/bin to your path: export PATH=$PATH:UNPACKED_PATH/jdk1.8.0_221/bin (replace unpacked path with actual path)
- start binder/template installer with:
java -jar XXX
UNPACKED_PATH/jdk1.8.0_221/bin/java -jar einkpads-binder.jarand put this into a .desktop file :-)

- if you accidently installed the new version, remove it with
sudo apt purge openjfx.
- Install an older version with
sudo apt install openjfx=8u161-b12-1ubuntu2 libopenjfx-jni=8u161-b12-1ubuntu2 libopenjfx-java=8u161-b12-1ubuntu2.
- To prevent the software updater from installing the newer not supported version, mark it to be not updated with
sudo apt-mark hold openjfx libopenjfx-jni libopenjfx-java.
Debian Buster (using packages from stretch)
It is most likely better to follow the general steps above and not add the stretch repository to apt...
Requires some special love, since version 8.X of openjfx has been dropped completely from buster, but right now we still need it for binder/templateinstaller to work. The ppa providing oracle jdk doesn't have java8 anymore as well, as oracle now requires a login for a download... (see https://launchpad.net/~webupd8team/+archive/ubuntu/java). But for now we can use the packages from stretch (the previous debian version)
Therefore proceed with caution and no guarantees given ;)
Add stretch repo
remove openjfx11 if already installed:
sudo apt remove openjfx
sudo apt autoremove
/etc/apt/sources.list.d/stretch.listwith the following content:
deb http://ftp.de.debian.org/debian/ stretch main contrib non-free deb-src http://ftp.de.debian.org/debian/ stretch main contrib non-free
deb http://security.debian.org/ stretch/updates main contrib non-free
sudo apt update
sudo apt -t stretch install openjfx
sudo apt-mark hold openjfx libopenjfx-jni libopenjfx-java
Do you have a Ubuntu 20.04 install document?
