Dear Maintainer,

   * What led up to the situation?

If I click on the icon of arduino, nothing is happening. In top I see only
for a short moment something with Java.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

After starting from icon was not working, i tried starting from Mate-Terminal.
Result was the following message, before returning to prompt:

Picked up JAVA_TOOL_OPTIONS:
Set log4j store directory /home/sven/.arduino15

   * What was the outcome of this action?

Nothing

   * What outcome did you expect instead?

That program is starting

Hi Sven, thanks for reporting. Sadly, I'm unable to reproduce the
stated behaviour. Wild guess would be that you are missing one of the
Java native libraries somehow. I would suggest:

 1. Reinstall package 'openjdk-11-jre'. The report says you've got it
already installed but people with a similar error were missing that
particular package [1].

 2. Reinstall packages 'arduino' and 'arduino-avr-core'. Maybe a
misconfigured arduino app is looking at the wrong places?

 3. Try installing 'openjdk-11-jdk' if it is not already there. Maybe
the arduino package is missing a dependency?

Hi Sven, I'm out of ideas here then. Thanks for trying.

Dear Java team, could you please comment on what could be causing the
reported error [1]? I'm unable to reproduce it and maybe you come up
with some ideas to troubleshoot?

Thanks a lot,

Hi,

the starting wrapper /usr/bin/arduino is simply using 'java' as the
binary name to call the JRE binary but does not check if the binary in
the path is usable or suitable.

Sven, you could please check where /u/b/java is pointing to? It should
look like this.

I've recently discovered similar problems elsewhere and I needed to
reinstall the openjdk packages. So it's possible that some symlinking
isn't correct.

It's also possible that something is changing the variable JAVA_OPTIONS
that is finally used in the wrapper.

You can simply add a line like this right before the last line in the
wrapper script.

Then please call arduino again from CLI.

You can also use 「readlink -f $(which java)」, which finds
the java binary from $PATH. Do also manually inspect the
output of 「which -a java」 which shows all java binaries
reachable from $PATH, and whether any of the environment
variables, like $JAVA_HOME, are set (they shouldn’t, in a
normal Debian installation with one JRE installed).

You should use update-java-alternatives for that.

I expecting something like this, at least that somehow openjdk-8 was the
root of this problem.
We need to narrow down if openjdk-8-jre is really the problem and how to
ensure users have also installed openjdk-11-jre to get Arduino IDE working.

Or 17?

If you need to ensure a minimum version, do this (/bin/sh-safe):


if test "$(java -XshowSettings:properties -version 2>&1 | \
    sed -n '/^    java.version = \([0-9]*\)\..*$/s//\1/p')" -lt 11; then
	echo >&2 "E: Either no JRE found or JRE too old (<11):"
	java -version
	exit 1
fi


The command substitution evaluates to the first number before
a period in the version, which is either 1 (from 1.8.x) or 8
for JRE 8, 11 for JRE 11, and obviously larger for later ones.
If none, it evaluates to empty, which test … -lt interprets as
zero which will also work.

Please submit this to the Arduino IDE maintainer.

Dear Maintainer,

I'trying to run the arduino-ide. Launching it from the menu did not
work,
I had version 2:1.8.13+dfsg1-2 . Now I updated to version
2:1.8.19+dfsg1-1,
but nothing changed.

Reading the conversation, I did the following:
# apt install openjdk-11-jre
# apt install openjdk-11-jdk

But I keep on receiving:

$ arduino

Somewhere on the net I found some hints suggeting to avoid using

but I do not know how I can choose...
