** I am not a Linux expert.
I have spun a Debian 10 VM in GCP which i need to access like in a GUI mode and be able to download and install some required applications for development and experiment purposes.
I think i have installed xrdp, display GUI packages, firefox, apache2 etc, but not able to land into GUI mode or browser mode.
1- I can't invoke/run firefox with "Display" error - Error: no DISPLAY environment variable specified
2- RDP from my local laptop also being refused with "connection refused" error.
Need some help.

I need a virtual desktop to access chrome on the go via the Chrome Remote Desktop app on IOS.
The virtual desktop should be the usual GUI where I can open / install programs like a normal PC.
I know Windows is not free hence I am stuck with linux.
I created account and I know I need to create an instance.
What instance? How to get GUI? How to setup and access using Chrome Remote Desktop? Etc
Totally clueless.
What I Did:
1) I installed a Ubantu instance with a disk space of 30G.
2) I went into the shell and tried to run commands for installing a standard GUI.
sudo apt-get install ubuntu-desktop
3) Immediately received errors of missing dependencies.
I am building a .net core 2.0 console app on windows 10 but I want to debug it on a remote linux server running debian 9.
I found this article:
https://blogs.msdn.microsoft.com/devops/2017/01/26/debugging-net-core-on-unix-over-ssh/
but where I get stuck is selecting the SSH connection. My remote server has authentication and if I enter the user#ip:port it doesn't find anything.
I found some mention of using SSH tunnelling but as there is no dotnet process listening on the server (it's installed but it doesn't have any listening service running I can see) I am unsure exactly what port I'm meant to be tunnelling or even which direction to tunnel it.
What do I need to do to get my SSH connection visible in the debugger?
I just tried this and I found that the Find.. button doesn't do anything either.
First you enable SSH connections in your Linux host (in my case, Ubuntu, I had to run sudo ufw allow ssh). Test things out by opening cmd on Windows and doing ssh user#host.
Then, on Visual Studio, in the SSH attach to process window, make sure you hit "refresh" and check the "show processes from all users" box. You should see the "dotnet" process running.
EDIT: you should be prompted for the remote host's password at some point. Here's the dialog shown when I changed the password on the remote host and then attempted to debug.
I have to set a development environment on a ubuntu machine(16.04).
It's django+postgresql+Nginx, I.think I could install all these things together on that machine，but I totally don't have any idea about how to connect it by using pycharm running on my pc, and how to manipulate the database.
Is there anyone could tell me how to connect it. This is the first time I have to use a remote machine.
By the way, my pc and ubuntu machine are in the same LAN, but there is another person who were asked to write db are not.
I hope I could get some suggestions from the community.
One of the best and common way is to use SSH.
Here you can find an official guide on how to enable SSH server on Ubuntu 16.04
You can use Putty to connect from Windows PC to your SSH server or if you're using Mac or Linux, there should be already installed SSH client. So, just ssh username#servername
Use SSH. Assuming you're on Linux, open a terminal and type:
ssh username#local-ip-address-of-machine
and then type your password when prompted. Your terminal window essentially acts as a terminal on your remote machine. From here, I suggest you research Docker in order to set up a custom environment for your Django project. I have only told you how to connect since that's your question, and there are plenty of tutorials on setting up Django and Docker. If the other person wants to connect, you will need to port forward on your router port 22 on the local IP of the machine.
If you haven't got SSH set up, this page tells you how.
Does anyone know if it is possible to run python-gui apps, like wxPython, on a c9.io remote server? I have my home server set up with c9 via SSH, and no issues logging in and running apps in the terminal on the VM. However, when I try to run GUI apps, I get the following error message.
Unable to access the X Display, is $DISPLAY set properly?
After searching and searching, I can't seem to find a guide or anything in the docs that detail how to set $DISPLAY in the script. X display is installed and active on my server, but I don't know how to configure the c9 script to access it properly. Any assistance would be appreciated!
I don't know if Cloud9 supports it but normally to run a remote GUI application you would have ssh forward the X11 communication over the ssh connection via a tunnel. So basically the application is running on the remote system and it is communicating with a local X11 server which provides you with the display and handling of the mouse and keyboard.
If you run ssh with the -X parameter then it will attempt to set up the X11 tunnel and set $DISPLAY in the remote shell so any GUI applications you run there will know how to connect to the X11 tunnel. Bw aware however that this is something that can be turned off on the remote end, so ultimately it is up to Cloud9 whether they will allow you to do this.
Apologies if this has been asked already, searching the web reveals lots and lots of threads about installing the Win8 beta on VMware but not the other way around.
I am trying to install VMware Server 2.0.2 on a Windows 8 Preview machine. It appears to install correctly but I cannot then reach the web based homepage to configure virtual machines, i.e.
https://localhost:8333/ui/
gives the error that the "connection attempt to localhost was rejected. The website may be down or your network may not be properly configured".
Has anyone had any success running VMware Server 2.0.2 on Windows 8 Preview? If so were there any gotchas you needed to avoid?
I don't think it will ever be resolved. VMware Server was declared End Of Availability in January 2010; There will be no support for Windows 8.
Your best try would be trying launching the services in compatibility mode, but why would you do that? Why not use the much more advanced VMware Player or VMware Workstation products?
I've found a way to run it on Windows 8.
On my PC with a x64 version of Windows 8, when I installed VMware Server 2, I found there was a service called VMware Host Agent that cannot be run. When I opened the system Service Manager and clicked to launch this service, it gave me the error.
My solution is to create a service with the same command string and set it to start automatically by using the "sc create" command in cmd.exe. And it worked for me!
