I'm not sure they had completed the migration to v3 at that point and it was still a mixed v2/v3 setup. Pretty sure by 21.04 it was all v3. Ubuntu-20.04: Python-3.8 is default, python-3.9 is available. Inkscape depends on python2:any. dpkg -S /usr/bin/python python-is-python2: /usr/bin/python I have not noticed any problem with python3. If some packages are considered as too old, e.g. Emacs-26.3 then Ubuntu-21.10 should be considered. At least it will be possible to upgrade it to Ubuntu-22.04 LTS in a single hop. Another option for rare upgrades is Debian stable. One thing I do find useful is to upgrade a virtual first. I use virt-manager to create a virtual machine running my current version and then upgrade that to see how the upgrade goes. I tried Ubuntu-20.10 and Ubuntu-21.10 in qemu. With the former I faced a really weird bug with depressed shift in gdm3 password field (you have no chance to notice that only first letter typed with shift is capitalized), with the latter firefox does not always redraw tabs after switching them using Ctrl+PgUp or Ctrl+PgDown. Booting live image directly works better and allows to test hardware support, e.g. sound. I have not tried 21.10 in this way, with 20.10 default wayland session cursor on the external monitor was too huge to make point where it points to rather uncertain. Problems with upgrade are usually caused by rarely used packages. So unless precise configuration is tried (dpkg --get-selections, dpkg --set-selections, third-party packages), the problem will not be noticed in VM. On the other hand installing all packages makes image size noticeably large. That issue I could solve meanwhile but only to receive another error ipython3 from my Ubuntu distribution but that corresponds to python 3.5 not 3.6 hm, ☹️ ipython may be installed to python 3.6 as well.

I'm not sure they had completed the migration to v3 at that point and it was still a mixed v2/v3 setup. Pretty sure by 21.04 it was all v3. While I do find upgrades to a new version can be very disruptive if it is left for a few versions, updates to the next version has been minimally disruptive for me. I guess a lot depends on how much 'extra' stuff you install and what tweaks you do, but for the last few years, I've found the upgrades quite painless. A lot depends on what changes - for example, I expect the update to 22.04 or maybe 22.10 will be more disruptive due to the move to pipewire for sound. One thing I do find useful is to upgrade a virtual first. I use virt-manager to create a virtual machine running my current version and then upgrade that to see how the upgrade goes. In fact, I tend to maintain a VM which is the same as my current version and whenever I need to make some potentially disruptive upgrades or configuration changes - such as updating org to a new version or try out the latest Emacs, I do that on the virtual machine first. This way, I don't interfere with my core system and configuration and have time to investigate any issues before doing the same on my core system.

Right, I installed python3.6 from a ppa, and that increased the mess. I uninstalled python3.6, also had to uninstall and then reinstall ob-ipython before I got rid of that error. smime.p7s Description: S/MIME cryptographic signature

From mails to this list my impression is that 5-years old OS generates enough compatibility problems to seriously consider newer LTS version. Support of python-2.7 and early 3.x version has been seized as well.

Since you are using ipython, do you have it installed for python versions you are trying?

I learned the hard way not to mix distro installed Python with pip installed Python.

Version issues are the most frustrating aspect of Python and one reason I've never embraced the language. Given that Ubuntu 16.04 was end of life in April 2021, my recommendation would be to upgrade to ubuntu 21.04. That version seems to have a more consistent Python environment (based on v3). It also has newer ciaro, hafbuzz and other libs used by Emacs which will likely work better and once Emacs 28.0 is released, will have the gccjit libs necessary for native comp etc.
