Arun Babu Neelicattu 75536e9b5d installer: use venv and improve error handling (#4099) ... * installer: improve error handling and logging Co-authored-by: Bjorn Neergaard <bjorn@neersighted.com> * installer: default to using in-built venv module This change refactors virtual environment creation and introduces a new wrapper to handle command execution etc. If venv module is not available, in cases like that of the ubuntu distribution where the module is not part of the default python install, the virtualenv package is used by fetching the appropriate zipapp for the package for the python runtime. Resolves: #4089 Resolves: #4093 * ci/installer: upload failure logs * installer: preserve existing environment on failure This change ensures that if creation of a new environment fails, any previously existing environment is restored.
