I want to run some tests with latest Chromium but experiencing errors.
I set up a new ubuntu 20 server without any additional packages.
Install chromium with apt install chromium-browser
Installed xvfb server
Created a display with
export DISPLAY=:2
Xvfb $DISPLAY -screen 0 1024x768x16 &
started chromium with
chromium-browser https://google.com
Error log shows:
2022/10/09 15:21:38.283814 cmd_run.go:1055: WARNING: cannot start document portal: dial unix /run/user/0/bus: connect: permission denied

Any hints how to fix that?

I use rabbitmq-server in Ubuntu 18.04.
I install rabbitmq-server through "sudo apt-get install rabbitmq-server"
And i run rabbitmq-server.service through "sudo systemctl start rabbitmq-server.service"
then, i checked "netstat -ntlp", cause port open(5672, 15672).
However, the following error log occurs.
=ERROR REPORT==== 24-Jan-2022::13:52:48 ===
Error on AMQP connection <0.5608.0> (127.0.0.1:45718 -> 127.0.0.1:5672, state: starting):
PLAIN login refused: user 'test_rabbit' - invalid credentials
What is the reason for this error and is there a solution to it?
I think I'm missing one step in the script below.
The first time I run it, the VM gets created just fine, but the connection is refused. It continues to be refused even if I wait ten minutes after creating the VM.
However, if I use the GCP console to connect manually "Open in browser window", I get the message "Transferring SSH keys...", and the connection works. After this step, the script can connect fine.
What should I add to this script to get it to work without having to manually connect from the console?
#!/bin/bash
MY_INSTANCE="janne"
MY_TEMPLATE="dev-tf-nogpu-template"
HOME_PATH="/XXX/data/celeba/"
# Create instance
gcloud compute instances create $MY_INSTANCE --source-instance-template $MY_TEMPLATE
# Start instance
gcloud compute instances start $MY_INSTANCE
# Copy needed directories & files

Edit: adding gcloud version info
(base) bjorn#ubu-dt:/media/bjorn/data/celeba$ gcloud version
Google Cloud SDK 269.0.0
alpha 2019.10.25
beta 2019.10.25
bq 2.0.49
core 2019.10.25
gsutil 4.45
kubectl 2019.10.25
The solution I found is this: wait.
For OS login, SSH starts working about 20 seconds after the instance is started.
For non-OS login, it takes about a minute.
So I just added this after gcloud compute instances start $MY_INSTANCE
sleep 20s
When you connect through Console it manages the keys for you.
Your last comment leads me to believe that when you connect from console you are generating an SSH key and it somehow allows you to run the script, I would recommend you to take a look at how to manage SSH keys in metadata and creating your own SSH key to access through the SDK.
If outside of the script through the SDK you cannot directly SSH either then I assume that it's because of the same reason of the generated key.
Also please make sure that when using the SDK the service account has the correct permissions.
Let me know.
Vscode insiders stopped to work with remote today morning after (unavoidble) update. It doesn't show remote directory, saying
Connection error: Unauthorized client refused.
and
Failed to connect to the remote extension host server (Error:
Connection error: Unauthorized client refused.)
Deletion of all remote vscode files and killing vscode processes didn't help.
The following transcript can be seen in Output tab:

But while running one script and it needs to login as root via ssh, it returns the error 'Permission denied (publickey)'.

I don't know why the script cannot automatically login via root without entering the password.
Please help! Thanks!
