extensions exist on remote box , but are shown as missing; extensions.json is an empty list

Question

I have a VirtualBox instance (Debian12) under Windows which serves as an Ansible controller.

I want to use it from Windows via VSCode ssh-remote and have a hard time to install any extensions on the remote box.

VSCode is

Version: 1.88.1 (system setup) Commit: e170252f762678dec6ca2cc69aba1570769a5d39 Date: 2024-04-10T17:41:02.734Z Electron: 28.2.8 ElectronBuildId: 27744544 Chromium: 120.0.6099.291 Node.js: 18.18.2 V8: 12.0.267.19-electron.0 OS: Windows_NT x64 10.0.19045

The extensions seem to exist:

norbert@ansible-vb-pelikan:~/.vscode-server$ ls extensions/
extensions.json  ms-python.debugpy-2024.4.0  ms-python.python-2024.4.1  ms-python.vscode-pylance-2024.4.1  redhat.ansible-24.4.0  redhat.vscode-yaml-1.14.0

extensions.json is an empty list:

cat  extensions/extensions.json 
[]

When I start the connection vscode shows the extensions as missing for several minutes, consider the attached screenshoz

Then after a long time the extensions show up as installed .

What is up ere ? How can I investigate further ?

I copied some extensions over to the remote host and thought they would be installed. I also set "remote.downloadExtensionsLocally": true. The network connection of the remote box seems to be fine in IPV4 and IPV6

Thanks for your consideration !

Answer 1

It was indeed a network problem. The IPV6 connection was flaky and IPV6 seems to be preferred if it exists
