I've just done a fresh install of ubuntu 18.04, and installed josm from the standard ubuntu repositories. Josm is not working properly. Initially it was failing to launch, and would return the error.
Then it was starting but was unable to connect to the internet, so couldn't download any data, or upload any changes. The error message provided is: Any recommendations to fix this? |

The "answer" I think is in the discussion on this other answer. As @aseerel4c26 and @keithonearth found, the problem isn't actually with JOSM itself (or that the JOSM shipped by Ubuntu is too old), but seems to be that Ubuntu broke CACERTS in 18.04. As noted at JOSM, see this bug at Ubuntu (and notice there's a release tracker at the top of that). Ignore the JDK version in that bug title, it apparently applies to them all.

Thank you @SomeoneElse for the the help figuring this out, and summarising the solution with this answer. I'll add some detail to your answer. I've successfully gotten Josm working on Ubuntu 18.04. My original issue related to Josm not detecting Java 11, but this seems to been fixed by the developers. At least it wasn't an issue for me after adding the josm repository, and updating. The second issue was more troublesome. I followed the workaround described by Antti S. Lankila in the link you provided. Here's a summery.
The instructions I was following recommended, upgrading to openjdk-9, but neither this nor openjdk-10 is provided in the standard repositories, and Josm is not complaining about the old version of Java, so I've left it as openjdk-8-jdk. So far this has not caused any issues.

I guess that JOSM in the standard ubuntu repositories is (way) too old. Which version is it? JOSM is compatible with Java 10 since version 13520 on 2018-03-12. Uninstall your current JOSM and instead try the current "tested" version of JOSM from the JOSM homepage https://josm.openstreetmap.de/ or add the JOSM repository to your APT system. Also see https://wiki.openstreetmap.org/wiki/JOSM/Linux#Debian_.28includes_Ubuntu.29 . 1
I've added the josm apt repository, and now have version 13576 installed. It is booting up from the menu, the command line, and from the jar file. But in all cases it is unable to connect to the internet. I have installed Oracle Java, 8 & 10. When starting it gives the error (I couldn't copy-past the error, so that may contain typos) Any clues?

@aseerel4c26, thank you for your comment. I've been checking on the but report every few days, and updating josm-latest from josm's repositories frequently. It's not fixed yet for 18.04, but should be soon.

If I'm reading the links correctly then the release tracker is https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/1739631 .

Thank you @SomeoneElse! That link was very helpful. I've successfully gotten Josm working for the first time since installing 18.04. I followed the workaround described by Antti S. Lankila in your link. While I've strayed from my original question, and probably should have asked a new question, here is what I did in case it helps someone:
The instructions I was following recommended, upgrading to openjdk-9, but this was not provided in the standard repositories, and Josm is not complaining about the old version of Java, so I've left it as openjdk-8-jdk.

@keithonearth I'd actually suggest that you add that as an answer. I tried to summarise a "correct" answer below but yours has far more detail. FWIW I suspect (based on what the Ubuntu bug says) that you should be able to go from openjdk 8 back to openjdk 10 after fixing CACERTS. Edit: Yes, JOSM will run with openjdk 10 after doing this. Also note that https://josm.openstreetmap.de/ticket/15851 is still being updated, monitoring the progress (or lack of it) of the Ubuntu maintainers towards a root cause fix.

Another answer seemed unnecessary, seeing as there was nothing wrong with yours, but I added an edited version of my above comment to your answer, and marked your answer correct. I think this will make the solution easy to find, if others come looking.

The script in /usr/bin/josm is falling to detect the jre from the new 18.04 release. If you run the jar directly it works ok: java -jar /routetojar/josm.jar usually /usr/share/josm/josm.jar No, "java -jar /usr/share/josm/josm.jar" does not work on a newly-installed 18.04 system with josm from apt (josm 13576). JOSM gives its confused "proxy" message because it can't retrieve stuff.

The script needed an update to detect Java 10 and 11. This is done in version 13700. This version should be released soon (within a week max). Just to keep this answer up to date, the "trustanchor" issues (see Keithonearth's comment above) still occur and it still doesn't run. Full details at https://josm.openstreetmap.de/ticket/15851 .

Still waiting on a fix. Still JOSM does not work on Ubuntu 18.04. You can get it to run by running the jar file directly but it cannot connect to the internet. Did you try the solution provided by SomeoneElse, that I expanded upon?
