user: Current not implemented on linux/amd64" $HOME=/home/ngrok

[mo-mueller]

I'm following this tutorial to publish a local RocketMap to the web with ngrok: https://rocketmap.readthedocs.io/en/develop/advanced-install/docker.html#advanced-docker-setup

Here are the 2 commands regarding ngrok: https://rocketmap.readthedocs.io/en/develop/advanced-install/docker.html#external-access

The RocketMap is running correctly, but the ngrok container logs this to me:

t=2017-08-03T18:43:32+0000 lvl=warn msg="failed to get home directory, using $HOME instead" err="user: Current not implemented on linux/amd64" $HOME=/home/ngrok

How can I fix that?

[smebberson]

I get this issue too.

[wernight]

Did you change the default user? May be give part of the command you ran and I'll look into it.

[leslie-qiwa]

I get this issue. this is what I got

# ngrok http 80
WARN[01-04|20:44:42] failed to get home directory, using $HOME instead err="user: Current not implemented on linux/amd64" $HOME=/root

[wernight]

What the command line you're running? I think setting HOME should fix it, e.g. --env HOME=/home/ngrok or may be ENV HOME=/home/ngrok in the Dockerfile.

[BeeHiveJava]

Hey @wernight, this issue seems to still be there for me as of today. I have tried various things:

• Setting the home directory manually
• Changing the default user
• Setting permissions

I'm really not sure where the issue is coming from. If you, or anyone else, seemed to have fixed this, please let us know!

[Caroga]

Same here, setting HOME via ENV or anything does not resolve this issue. Any ideas?
Command is
docker run -p 4390:4390 --name ngrok-tunnel --link development_web_1 wernight/ngrok ngrok http development_web_1:80

[wernight]

Thanks for sharing the command that fails.

I do see the warning with: docker run wernight/ngrok ngrok http 8080. However it seems to work. I'll look in fixing that warning if possible.

[wernight]

I think I fixed the warning. Note also that running in interactive mode seem to also fix the issue (i.e. with -it).

[gonzalom]

In my case, setting the variable USER fixes the problem:

USER=root

Changing the user for yours, and using the environment variable assignation of your choice:

• Export before run: export USER=root && ngrok version
• Assign when running: USER=root ngrok version
• Dockerfile: ENV USER=root
• docker command: --env USER=root
  etc.

[wernight]

Note that the default user is ngrok and not root. Doesn't that default user work for you?

[jay341-py]

./ngrok http 8080 WARN[01-13|17:19:22] failed to get home directory, using $HOME instead err="user: Current not implemented on linux/arm"

I have this type of error
Please solve this.

[tindurz]

Need this command

export USER=$(id -un)

[gonzalom]

Note that the default user is ngrok and not root. Doesn't that default user work for you?

Sorry @wernight, I missed your message.

I didn't tried, I can't tell right now, but it would be a matter of test it, or try @tindurz solution: export USER=$(id -un)

[0xygyn]

You can try this.
echo $HOME
echo $USER

Then

set $USER = $HOME

Then

./ngrok http 80

[vardipoorm]

#Need this command

export USER=$(id -un)

Solve my problem thanks
