Upgrading the base image to Ubuntu 26.04 is premature and will break the build. Ubuntu 26.04 is not yet a stable LTS release, and the image may not be available in the mirror. Furthermore, older Python versions (such as 3.7, 3.8, and 3.9) defined in PYTHON_VERSIONS will fail to compile on newer Ubuntu versions due to toolchain upgrades and the absence of older OpenSSL versions (like OpenSSL 1.1.1) which these Python versions require. Other installations, such as the Microsoft ODBC driver (currently configured for Ubuntu 20.04) and Chrome/Chromedriver, may also be incompatible. Please stick to the stable Ubuntu 24.04 LTS release.
