I am also facing the same issue. I am also in Ubuntu 16.04 LTS.

I tried to downgrade the python extension to previous versions, but then the debugger will not start(no error shown on this case just. Terminal will show the initial debug command and it will not get executed).

I suspect this an OS related issue because on my laptop which is using Ubuntu 18.04 LTS doesn't have this issue.

This my launch.json.

   "version":"0.2.0",
   "configurations":[
      {
         "name":"Python: Current File",
         "type":"python",

         "console":"integratedTerminal",

      },
      {

I'm getting the same error on MacOS Catalina

I have the same error connecting from both Windows and MacOs, but using the remote extension to connect to a ubuntu 16.04 machine. And I just tested with the previous version of the python extension and for me, it works normally.

@fieraloca You've mentioned that you're hitting this issue with conda as well as system Python. For the latter, are you also creating virtual environments? Does it still happen if using the system interpreter directly?

[omartin2010]

In my case it happens without virtual envs. Straight os python3. Get Outlook for iOS<https://aka.ms/o0ukef>

@int19h I have tried with both system python (with and without virtualenv) and with conda environments for python 3.5; 3.6 and 3.7. Same failure in all cases...

[Shannon33]

I'm getting the same error on MacOS Catalina when I using the remote extension to connect to a ubuntu 16.04 machine.I can't debug,I got the error message "timed out waiting for <debugpy.adapter.components.missing..Missing object at 0x7fb9e2753cc0> to connect"

[omartin2010]

temp workaround is to go back to previous version. Worked for me.

[Shannon33]

@omartin2010 thank you very much! I choose to go back to previous version,it work! Just change the extension of python (ms-python.python),the mistake will solve.

Here is what took me to fix the problem in Ubuntu 16.04

reference sites: https://stackoverflow.com/questions/37071388/how-can-i-install-visual-studio-code-extensions-offline

Step 1. Get a previous version of vscode

• uninstall all and every version of vscode from you PC. (don't ask why; just do it !)

• launch browser with https://code.visualstudio.com/updates/v1_42

• click the [deb] link under Linux
  Downloads: Windows: User System | Mac | Linux: snap deb rpm tarball

• save the file to your Downloads folder. it should be named "code_1.42.1-1581432938_amd64.deb"

• navigate to Downloads; right-click the ".deb" file and select "Open with software installer"

  this will install vscode

• launch vscode and update your settings to disable auto update ( Do not select None; if does not work in ubuntu; use manual instead)

  File/Preferences/Settings/Application/Update
  Mode : Manual

Step 2. Get ms-python.python extension

• download ms-python extension manually using the following link

https://ms-vscode.gallery.vsassets.io/_apis/public/gallery/publisher/ms-python/extension/python/2019.10.0/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage

I played with few versions until I got one to work; be may guess and try to match the best one for your needs; I selected 2019.10.0 because this is the day the mantis ate the cricket...

• the file is downloaded as Microsoft.VisualStudio.Services.VSIXPackage

• add a file extension to the file (right-click/rename) to be Microsoft.VisualStudio.Services.VSIXPackage.vsix

• launch vscode. Please ignore any attempts to update; if you do, you will be back to square one.

• select the Extensions tab (Ctrl-Shift-X)

• click the "..." (More Actions... ) at the top of the tab, to the right of "EXTENSIONS"; Select "Install from VSIX"

• select your VSIX package from Downloads (before you click Install, clap 3 times with the back of your hands... proven to work every time!!! )

• your extension will be installed. ( I have selected 2019.5.18875).

• DO NOT CLICK THE "Update to 2020.3..." beside your Python package.

• Happy coding.

microsoft/debugpy#84 is the primary issue tracking this bug now, so I'll close this one as a dupe.
