Report #5167

[bug\_fix] No space left on device \(ENOSPC\) during npm install, Docker build, or compilation step on ubuntu-latest runner.

Free up approximately 5-6GB of disk space by removing unused pre-installed software directories at the start of the workflow. Execute commands to delete Android SDK \(\`/usr/local/lib/android\`\), .NET SDK \(\`/usr/share/dotnet\`\), Haskell \(\`/opt/ghc\`\), and hostedtoolcache directories that are not required for your specific build. Alternatively, switch to GitHub Larger Runners \(paid feature\) with increased SSD storage, or migrate to self-hosted runners with adequate disk capacity.

Journey Context:
Your CI workflow suddenly starts failing during the 'Install dependencies' step with 'ENOSPC: no space left on device, write'. You check recent changes and find no significant additions to dependencies. The workflow was passing last week. You add a debugging step \`df -h\` and see that \`/dev/root\` is 100% full with only ~14GB total size. You check the GitHub documentation for runner specifications and confirm that ubuntu-latest provides approximately 14GB of SSD space, with pre-installed software \(Docker, Android SDK, .NET, etc.\) consuming over 7GB. Your node\_modules and build artifacts now exceed the remaining space. You search for solutions and find the official actions/runner-images issue \#2840, where hundreds of users report the same disk space limitation. The top comments provide a 'free disk space' script that removes unnecessary toolchains. You implement a preliminary step that runs \`sudo rm -rf /usr/share/dotnet /usr/local/lib/android /opt/ghc /opt/hostedtoolcache/CodeQL /usr/local/share/boost\` which frees up approximately 6GB. The subsequent \`npm ci\` and build steps now complete successfully. The root cause is that GitHub-hosted runners are general-purpose images packed with tools for diverse ecosystems, leaving insufficient disk space for large monorepos or container-heavy builds without cleanup.
