Interesting for me too as I'm coming back to the linux world after a long gap. I have installed Anaconda , the 32 bit one and am happy to be able to do my coding locally as opposed to going on the cloud. Gouri On Fri, Apr 19, 2019, 3:59 PM o1bigtenor via talk <talk@gtalug.org> wrote:

Thanks for the warning.
This relates to my lightning rumination: "what is a distro?"
As a Linux user, it has been very convenient to delegate several software maintenance tasks to the distro:
- selecting - security auditing - configuring - testing - bug fixing - updating
I'm not sure what you mean by 'updating'? Are you expecting the distro to schedule the update? Do you want the distro to inform you of newer versions? Hmmmmmmmm - - - please?
I may not agree with all their choices, but it sure makes life easier. I pick a distro based on how happy I am with the distro's choices.
Sometimes I install software that isn't provided by the distro. A little more work for me, but not a problem.
The trouble you mention comes from software that is partially from inside the distro and partly from outside. Python3 is part of Ubuntu 16.04. But, Anaconda, part of the Python system is not part of Ubuntu. I assume you install it with pip.
If you actually change how Python3 behaves (as opposed to just adding stuff), your distro's software could misbehave -- some is written in Python3.
Similar problems arise with TeX (CTAN) and with Perl (CPAN) and who knows what else.
Another variant of the problem arises when you need something more modern than what the distro provides. This is accute in RHEL because it is so focussed on stability.
I think that Canonical's "Snaps" (and flatpak.org's "Flatpak's) are meant to address this hard problem. I don't know how well this works.
