Ubuntu 20.04 LTS Continuing To Work On Python 2 Removal

[skeevy420]

Most of those rev deps are python2 packages, not really required once you get rid of Python 2. You should seriously consider git instead of mercurial and bzr.

I have to assume those were pulled in for building some AUR packages or via some IDE with cruddy version control dependencies. Those are the only reasons those ever get installed on my systems.

AsuMagic The package pahole-git should be rebuilt. It depends on python3 now (and has since at least May according to the AUR page).

How long do you go without rebuilding git based AUR packages? Over six months isn't good practice to get into.

inkscape and solaar is the only thing I use that need python2. Solaar is easy to just ignore but inkscape is worse. Is there any other reasonably good vector software to replace it?

There's WIP for mercurial. starting from mercurial 5 you can

HGPYTHON3=1 pip3 install --user mercurial

to get the python3 version. works ok for my very limited use.

Well, calibre, bleachbit etc. will be glad to hear that! :-)
.

BleachBit has already been ported to Python 3 and Gtk 3. So nice try.

One day hopefully.

You do realize that almost all of those libraries have had Python 3 ports for a long time now? So no need to keep the Python 2 ones around unless you use them for coding still.

On my laptop the list included bzr but I don't use that so I had to check:

:: removing bzr breaks dependency 'bzr' required by flatpak-builder

So I guess he also probably didn't use it himself but some other package required it.

Some Python 2 depedencies are from mythtv on my laptop. Apparently I had installed playonlinux which required wxpython, removed that.

Pretty sure they are in the list because some other software needed them.

On my laptop biggest culprits are gimp, inkscape, flatpak-builder (bzr) and mythtv.

The next version of inkscape is already ported to Python3. It is available on debian experimental (beta version).

So you'll probably be fine.

I'm just a student but why is end of life for a language a bad thing? People still code in C99 and Fortran and Cobol. Just because the language is old doesn't mean you can't write software for that standard right? Its not like say WIndows XP where security vulnerabilities exist that don't get patched anymore. It is just a programing language. What am I missing?

It also shows some on that list on my laptop, but I safely removed them now and everything is still running fine and stable: no other software was depended on it.
