Dev Containers does not work in 0.45.0

Bug Reports
1

Unfortunately upgraded to 0.45.0 few minutes ago:

Version: 0.45.0
VSCode Version: 1.96.2
Commit: f06cc5e62b757b2bf61ec052a8701fb2da9ded20
Date: 2025-01-20T19:17:28.428Z
Electron: 32.2.6
Chromium: 128.0.6613.186
Node.js: 20.18.1
V8: 12.8.374.38-electron.0
OS: Darwin arm64 24.2.0

After that it rebuild the current devcontainer and updated the extensions. After the window reload I stuck with the following message:

[7 ms] Dev Containers 0.394.0 in VS Code 1.96.2 (f06cc5e62b757b2bf61ec052a8701fb2da9ded20).

Hpw could one develope an

“upgrade_migration_repo” for agents…

A litmus of agentic continuity…

have a base account repo. Into it various aspects of your logic and outputs and context reside.

When adapting to a new model, new agentic platform, or a latest update - put the agents through validation testing and USER ACCEPTANCE TESTING that the IDE (which is now the agent) can seamlessly move forward and wont backward break â– â– â– â– ?

Should there be an agentic versioning handoff?

Are there internal release notes that can be back-propagated to the existing agentic install such as:

"Im about to update to this [URL to release code that agents can slurp] – and I want you to evaluate our @codebase for any adjustments that need be written/done/logged/communicated – and give me a detailed rollout with rollback.

(in major ■■■■ (give me a DR plan) etc…

sas 70 the agent. Sarbox the agent, etc…

Could you try uninstalling and reinstalling the extension.

And if that does not work, could you try removing the extension: rm -r ~/.cursor/extensions/extension-name, then reinstall. Then restart Cursor via cmd+shift+p > reload window

6

How do you even install the dev container extension? I’ve tried so much different versions and none will install or even be recognized by cursor…

try manually install it:

Hi!

We published our own extension for dev containers. If it’s still not working for you, could you try uninstalling the existing extension, and then install the Cursor remote containers extension? You can find it by searching for @id:anysphere.remote-containers in the extension search box. (Attaching a screenshot)

Hi! Could you check this error that occurs when I try to attach to the docker conatiner with anysphere.remote-containers?
my cursor version is 0.50.5, the extension version is 0.0.12

I can attach using vscode but cannot with cursor.

Hi @kiwicloooou, could you share the Dockerfile or docker image, and the dev container config that you are using? Thanks!

Thanks – I tried building a similar issue and wasn’t able to reproduce it. Would you be able to rm -rf /root/.cursor-server within the container, and try again?

If that doesn’t work, would you be able to create a new dev container? You can do so by running docker rm -fv <container id>. Note that this would cause any ephemeral state that is not stored inside a bind mount or named volume to be lost.

Thank you for checking. I’ll give that a try. Have a great day!
