Installation failed due to Xauth error about hnn HOT 23 CLOSED

Hi @lcmardell: thanks for including the log file. I'm hoping you can help with a little debugging so I can fix this for all users.

From what I can tell, an entry is not getting created in ~/.Xauthority. The hnn_docker.sh script can create the file and add the appropriate entry if the file doesn't already exist. Can you try deleting ~/.Xauthority and re-running the script? Even if that solves it, could you post the end of hnn_docker.log again?

Thanks!

from hnn.

hnn_docker.log
I have tried this a couple of times, deleting Xauthority and it still does not work - getting stuck at the same point.

from hnn.

The log shows that hnn_docker.sh thinks your home directory (returned by ~/) is /n/. Can you confirm that in the shell if you run cd ~?

The command /c/Program Files/VcXsrv/xauth.exe generate localhost:0 . created an Xauthority file somewhere, but it's not in ~/ where the script expects it to be. Can you find this .Xauthority file somewhere (maybe in the hnn directory)?

If the above cd ~ fails, what about temporarily setting the HOME environment variable?

export HOME=/c/Users/[YOUR_USERNAME]/

And then verifying cd ~ takes you to the right directory and finally retrying hnn_docker.sh.

Please report back with what you find. I haven't seen this before. Thanks

from hnn.

My home directory is /n/ and this is where hnn is downloaded. I've now tried moving it to /c/Users/[my username]/ and running hnn_docker again (also changed HOME), the same thing keeps happening, where Xauthority is always generated in my home directory but it still fails at Xauth.

Ok, perhaps this. I made the xauth command to be specific about which file to use in this commit. Can you test it by retrying hnn_docker.sh after the following?

git fetch origin pull/187/head:issue_186
git checkout issue_186

from hnn.

Have done

If it didn't work, could you send the log? Thanks

VcXsrv may be dying immediately after the script tries starting it which I found would produce what you're seeing. I've put more debugging into the pull request (try the fetch/checkout commands again). Try deleting ~/.Xauthority again.

You can run the xauth commands manuallly. The goal is to get this command to show a generated key:

/c/Program\ Files/VcXsrv/xauth.exe -f ~/.Xauthority list
[key]

Delete ~/.Xauthority. To generate a new key, VcXsrv must be running. Let's start it

/c/Program\ Files/VcXsrv/vcxsrv.exe -wgl -multiwindow 2>&1 &

It should still be running in the background. Run this command (the no such file error is expected the first time you run it)

/c/Program\ Files/VcXsrv/xauth.exe -f ~/.Xauthority generate localhost:0 .
bash: c/Program Files/VcXsrv/xauth.exe: No such file or directory

If you see this, then I suspect VcXsrv is crashing

C:\Program Files\VcXsrv\xauth.exe: (argv):1:  unable to open display "localhost: 0".

The log file might tell us why. Thanks for your patience.

from hnn.

hnn_docker.log

When I run the first line to generate a key there is just a blank response

`rmhklcm@CS00047600 MINGW64 ~/hnn (issue_186)
$ /c/Program\ Files/VcXsrv/xauth.exe -f ~/.Xauthority list

`
VcXsrv doesn't seem to be crashing

from hnn.

Oops. It looks like the fetch command I gave you can't be run twice. So the new code wasn't downloaded. I'm hoping the logs will give a clue as to why the generate command isn't working.

Try this instead.

git pull origin refs/pull/187/head

Then you should have the updates to hnn_docker.sh that will capture the output of VcXsrv.

This is still failing on the same part.

"Retrieving current X11 authentication keys... failed. Error with xauth: no valid keys
Please see hnn_docker.log for more details"

from hnn.

Thanks. I found a note in VcXsrv releases that they updated xauth, but when I downloaded the new version, xauth didn't actually get upgraded.
https://sourceforge.net/projects/vcxsrv/files/vcxsrv/1.20.6.0/

I'm trying to build VcXsrv myself to make sure it gets updated to version 1.1 and will report back. You could try the new VcXsrv version, but I'm not sure it will help.

export PATH=$PATH:/c/Program\ Files/VcXsrv/
xauth -V

Is there any text in ~/.Xauthority? Some of it won't be readable, but it should begin with your machine name.

Also, I know that you verified that xauth list didn't return anything. What about xauth nlist?

from hnn.

xauth -V is 1.0.1

This is the contents of .Xauthority:
�
CS00047600 �0 �MIT-MAGIC-COOKIE-1 �¶��³®5?º�âØá?÷kO

Neither xauth list nor xauth nlist return anything

from hnn.

Okay. The contents might be okay. I tried an update that will turn this into a warning and try continuing with starting HNN anyway. Could you try it again?

git pull origin refs/pull/187/head
hnn_docker.sh start

I'm still working on building VcXsrv with a newer version of xauth, but that may not be critical.

Ok great, it's now working. Thank you.

from hnn.

Excellent. I'm glad to hear that. Thanks for working with me on this. I'll incorporate those changes into a released version shortly.

from hnn.

Trying to get xauth 1.1 included in vcxsrv, but this may not solve the problem.

closing as the workaround in PR #187 has been merged.

Hi @blakecaldwell , I'm experiencing kind of the same issue.
On Windows 10 (not pro) when I run ./hnn_docker.sh -u start I get:

======================================
Upgrade HNN image requested

Starting HNN container requested

Performing pre-checks before starting HNN
--------------------------------------
Checking OS version... windows
Checking if docker is installed... done
Checking if Docker (Toolbox) is working... done
Checking Docker container type... linux
Downloading new HNN image from Docker Hub... done
Looking for existing containers... not found
Checking if VcXsrv is running... no
Checking for vcxsrv... found
Starting VcXsrv... done
Checking for xauth... found
Checking for X11 authentication keys... *failed*

For me, the command didn't create an .Xauthority file.
I followed your suggestion and ran:

export PATH=$PATH:/c/Program\ Files/VcXsrv/
xauth -V

The .Xauthority file was created this time (with content in it), but the start command still failed.

Here is the log file:
hnn_docker.log

Would really appreciate any help.

from hnn.

@ShiriMakov thanks it looks like an issue that came up in #228. I went ahead and merged this "fix" to master. Could you pull the latest code and try again? If there are still issues, could you comment in #228 and I can reopen that issue?

As a heads up, we will soon be providing instructions to install HNN in WSL and will not use docker after that. So hopefully fewer issues like this will crop up.

from hnn.

Thanks @blakecaldwell, will continue in #228 .
