I tried to fix this by using base:ubuntu image and adding features like ssh, conda
( base ubuntu doesnt come with conda, so it throws another following error if conda is not added)
The following has been added in your "/home/vscode/.bashrc" file
# >>> mamba initialize >>>
# !! Contents within this block are managed by 'micromamba shell init' !!
export MAMBA_EXE='/home/vscode/.local/bin/micromamba';
export MAMBA_ROOT_PREFIX='/home/vscode/micromamba';
__mamba_setup="$("$MAMBA_EXE" shell hook --shell bash --root-prefix "$MAMBA_ROOT_PREFIX" 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__mamba_setup"
else
alias micromamba="$MAMBA_EXE" # Fallback on help from micromamba activate
fi
unset __mamba_setup
# <<< mamba initialize <<<
2026-09-19 09:38:27.226Z: Please restart your shell to activate micromamba or run the following:\n

2026-09-19 09:38:27.266Z: onCreateCommand from devcontainer.json failed with exit code 127. Skipping any further user-provided commands.Hence, this configuration files need changes (mcr.microsoft.com/devcontainers/universal:2 image is old and downloads lot of unnecessary bloats, filling up space).
Steps to Reproduce
-
Click on the green <> Code button to create a codespace, click on three dots and select New with options.
-
Here, configuration will be set. Click on create codespace
-
Codespace creation begins. It takes few minutes (around 7-8). Observe creation log. Once it fails, it creates a recovery container (alpine image).
-
After codespace is created, check /vscode/workspaces/.codespaces/.persistedshare/creation.log for creation.log file. Here the issue can be confirmed.
