Update CI workflow to include apt update before package installation (#212)

jaybosamiya-ms · web-flow · commit 622a46d35c8d · 2025-07-15T17:26:33.000-07:00
Apparently, as per [GitHub Actions documentation](https://docs.github.com/en/actions/how-tos/using-github-hosted-runners/customizing-github-hosted-runners#installing-software-on-ubuntu-runners), we need to run `apt update` before `apt install`. We have not hit a particularly bad apt cache in our runner images (since GH Actions updates them very regularly) before, so we were able to save a tiny bit of time by not actually running `apt update`. However, apparently in PR #211 (see [this CI run result](https://github.com/microsoft/litebox/actions/runs/16306783607/job/46054462004?pr=211)), we actually hit a cache issue. This PR fixes this by always doing an `apt update`.
