Temporary Fix

Steps summarised by Copilot

• MongoDB Installation in GitHub Codespaces

Problem

The postCreate.sh script failed with exit code 127 because MongoDB's apt repository GPG key uses SHA1 signatures, which are rejected by security policies as of February 2026.

Solution

Replace the apt-based MongoDB installation with a direct binary download.

Steps

1. Update .devcontainer/installMongoDB.sh - Replace apt installation with direct download:

   #!/bin/bash
   
   MONGO_VERSION="8.0.4"
   MONGO_URL="https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-debian12-${MONGO_VERSION}.tgz"
   INSTALL_DIR="/opt/mongodb"
   
   curl -fsSL "$MONGO_URL" -o /tmp/mongodb.tgz
   sudo mkdir -p "$INSTALL_DIR"
   sudo tar -xzf /tmp/mongodb.tgz -C "$INSTALL_DIR" --strip-components=1
   rm /tmp/mongodb.tgz
   
   echo 'export PATH="/opt/mongodb/bin:$PATH"' | sudo tee /etc/profile.d/mongodb.sh
   sudo mkdir -p /data/db /var/log/mongodb
   sudo chown -R $(whoami) /data/db /var/log/mongodb

2. Update .devcontainer/startMongoDB.sh - Use the new paths:

   #!/bin/bash
   
   export PATH="/opt/mongodb/bin:$PATH"
   mongod --dbpath /data/db --logpath /var/log/mongodb/mongod.log --fork

3. Run the scripts:

   bash ./.devcontainer/installMongoDB.sh
   bash ./.devcontainer/startMongoDB.sh

4. Start the app:

   cd src && uvicorn app:app --reload

Alternatively, using apt instead of a tarball, this installMongoDB.sh can be used.

#!/bin/bash

# Install MongoDB
curl -fsSL https://www.mongodb.org/static/pgp/server-8.0.asc | \
   sudo gpg -o /usr/share/keyrings/mongodb-server-8.0.gpg \
   --dearmor
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-8.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/8.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-8.2.list
sudo apt-get update
sudo apt-get install -y mongodb-org

# Create necessary directories and set permissions
sudo mkdir -p /data/db
sudo chown -R mongodb:mongodb /data/db
