IntelliJ won't start up


I'm trying to install IntelliJ for the first time on a system running 64-bit Ubuntu 16.04. When I run I see some CPU activity, then it just stops. There are no error messages or output of any kind. I've tried v2018.1 (ideaIU-2018.1.1.tar.gz) and v2017.3.5 (ideaIU-2017.3.5.tar.gz). The SHA256 checksum for ideaIU-2018.1.1.tar.gz matches.

I found ~/.IntelliJIdea2018.1/system/log/idea.log, which contains some output but no errors:

What can I try to get it to start up?

Comment actions Permalink

Does the process terminate without errors in the terminal or does it hang forever?

Comment actions Permalink

It terminates without errors, after 10 or 15 seconds.

Comment actions Permalink

Can you try running from a different user or via sudo?

Comment actions Permalink

With sudo it started up and I went through the introductory setup.  I don't have another user to try.

So this could be a permissions problem?


Comment actions Permalink

Unfortunately, it's not clear what the problem is. We had one user with the similar issue, we were trying different things and didn't solve it. On a clean Ubuntu the issue cannot be reproduced.

I wanted to look for file permission problems so I ran strace:

$ strace -ff -e trace=file "./" 2>&1

The output ends with

I ran this a couple of times, and the section before the references to SIGALRM changed, but it always ended with many processes being killed by SIGALRM.

Do you use /home/scorwin/apps/java/jdk1.8.0_144 instead of the bundled runtime? Does it help if you switch back? See

Comment actions Permalink

It's the same behavior with the bundled runtime.  I actually started with idea-IU-181.4445.78 with the bundled 64-bit JDK, and only switched to using my own JDK while trying to troubleshoot this problem.

Comment actions Permalink

Can you try to trace what specific processes are started and killed (and their full command lines)? But it's not clear if it's related to the problem.

Comment actions Permalink

I'm having the same issue on a 64 bit xenial server install with trinity (kde3) installed.

Idea only runs as root.

Not happy.

Comment actions Permalink

I found a better workaround. The reason starting with sudo works is that there are fewer environment variables set. In particular there is this one:

If this is not set IntelliJ will start up successfully for me.

I created a shell script for convenience:
$ cat

The same approach works for running Android Studio.

Experienced also sigsegv when starting pycharm. I tried another jre and also a fresh download of pycharm (2018.3.5) but it kept on crashing.

➜ bin ./
# A fatal error has been detected by the Java Runtime Environment:

[thread 139638650844928 also had an error]
^CAborted (core dumped)

I resolved it by removing the pycharm folder in my ~:

➜ bin mv ~/.PyCharm2018.3 ~/.PyCharm2018.3_

Then it started again; seems some files got corrupted there and pycharm cant handle it.

Please report at with /home/paul/java_error_in_PYCHARM_4341.log attached.

Hi guys,


My intellij meet the same issue after upgrade to 2019.3.3. 

sudo ./ works but ./ not. Intellij quit peacefully. 

But after I run  "strace -ff -e trace=file "./" 2>&1", magic happened.  Intellij run without issue (but slowly with verbose log).

After Intellij stabilized and I closed the Intellij restart again without strace. My intellij works again!

so  thanks a log @Scorwin for save my day!

Same issue with PyCharm Pro 2021.1.1 on Ubuntu 20.04.

For me as well, this works with sudo.

I'm using docker containers for most of my python work and have the feeling that a container might have registered something as root.

PyCharm installed using `snap`, for what it's worth...

`strace` does not solve the issue for me, I fear.
Is there somewhere I could upload the strace log to? WIth 3.4mb it's too large for pastebin

We had several reports that Cortex XDR anti malware agent is affecting startup of our IDEs. Please try uninstalling it if you have one.

Comment actions Permalink

I'm not an expert, but something called *... anti malware agent* doesn't sound like a thing I'd like or should uninstall. Is there another way?


Comment actions Permalink

Ido Freeman You may uninstall Cortex XDR anti malware agent as a troubleshooting step. In case this program really prevents IDE from start, try to add IDE to the exclusions list or something like that. Choosing another antivirus is also an option. 


Comment actions Permalink

It seems like Cortex XDR is not installed on my machine

Any other antivirus? 

You may share console output, strace logs and whole issue descriptions at YouTrack:

There is a possibility that your case is different from the one discussed in this thread.

Nothing I've explicitly installed/ I'll make sure to open a new ticket.
