python3-volatile binary package in Ubuntu Lunar riscv64

 Volatile provides an alternative to tempfile.NamedTemporaryFile that does
 not delete the file on close(), but instead unlinks it after the context
 manager ends. It also supports temporary mkdtemp-based directories, and
 temporary Unix domain sockets.
 .
 It does not support custom schemes or signatures beyond what the Python
 Standard Library supports.
 .
 Volatile's API is documented in the comments of its source.
