Comment 5 for bug 1770391

"I am Taiwan user and new to Ubuntu, please forgive me for some wrong/inappropriate translations on wordings or terminology."

I installed JOSM from Ubuntu software today (about 7/24 UTC+8 20:30)

Click short-cut on GUI, JOSM appeared no action and terminated without launching on window/screen.

And I asked for help on forum, people suggest me enter

sudo josm

on terminal then results appeared No valid JVM found, I think this error appeared commonly on previous cases.

I generally did like this
for java runtime environment, I entered on terminal:
sudo ln -s /usr/bin/java /usr/local/bin/jamvm

However, I am not sure if it is essential since in Ubuntu 18 JRE should be worked initially,

Then in JOSM aspect, we adjusted these things:

sudo echo "deb https://josm.openstreetmap.de/apt trusty universe" >> /etc/apt/sources

[or replace as (echo "deb https://josm.openstreetmap.de/apt trusty universe" | sudo tee -a /etc/apt/sources)]

wget -q https://josm.openstreetmap.de/josm-apt.key -O- | sudo apt-key add -

sudo apt-get update

sudo apt-get remove josm josm-plugins

sudo apt-get install josm

some of the core technical info can be found on these two web pages;
https://josm.openstreetmap.de/wiki/Download#Ubuntu
and
https://josm.openstreetmap.de/wiki/HowTo/JOSM-under-Linux

however this bug or deficiency on JOSM/Ubuntu or may be very complicated for beginners to adjust themselves.

sorry for so long descriptions.
