I recently upgraded to 20.04 from 19.10. Now i face issues since i need to use a virtual environment with Python 3.7 and cant seem to install the packages: - Python3.7-venv - Python 3.7-dev
Seems like these are not supported by 20.04.
Any way to install them for 20.04? Would they still have worked if i didnt do autoremove during the upgrade?
I hope to avoid having to reinstall 19.10.
Rather than building from source or using packages from different Ubuntu versions I would recommend using the Deadsnakes PPA. This provides both newer and older versions of Python than are in the Ubuntu archive, and keeps those versions up to date with bugfix releases.
In Ubuntu 20.04, you will get bydefault Python 3.8 version. If you want to install Python 3.7, you can download python 3.7 tarball file and install it.
