where should DEFAULT_CIPHERS be found?

where should DEFAULT_CIPHERS be found, or
what do i need to upgrade (this used to work 2 or 3 years ago) ?

i've re-installed botocore. does this need Python > 3.8 (what Ubuntu 20.4 has) ?

There is a Deprecation notice for python 3.8 here. This message, claims support for 3.8 will continue for six months, finally ending Sept 1, 2022.

So looks like you may indeed have to upgrade.

now, to decide if i should try to upgrade Python to 3.10 on Xubuntu 20.4 or wait until other things ready me to upgrade Xubuntu to 24.4 with brings in Python 3.10. i do know some "system stuff" makes use of Python, so i am leaning to the later.

You could just use pyenv and install any version of Python you need. It is very straightforward.

pyenv is exactly what I use, It works very well.
Especially since you can use a different version of python, if necessary, for each project, in a virtual environment.

[Skaperen]

how will that work for system code while booting up? those who do use it, do you use it on Ubuntu Linux?

Try uv it replaces pyenv and lot more,it will(has) be the default choice for a Python package and project manager.
uv install python and it work on all OS also a lot faster than other stuff,eg see under it install Python 3.13.3 in 5-sec and Request 1-sec.

Are there any telemetry concerns with uv?
I'd like to give it a go.

No uv is a fully open-source (Apache/MIT) binary with no hidden telemetry back-ends.
