Suggested change

	- Ubuntu 22.04 or below
	Or, install via pip:

Installing via pip is still recommended, since new versions of pipx will be directly uploaded to PyPi and be pip-installable, in contrast to the version freeze in Ubuntu.
I'd tend to remove this line.

I’d even drop the and for other distributions part, most users should be smart enough to infer that?

[dukecat0]

See #982. Installing via pip may not work. Or maybe we can suggest users use pipx through zipapp?

curl -L https://github.com/pypa/pipx/releases/latest/download/pipx.pyz -o pipx.pyz
alias pipx="/path/to/python/interpreter pipx.pyz"

[uranusjr]

Sueggesting the pyz is probably the best thing to do. Instead of alias (which needs to be added to rc) it’s probably better to suggest adding a script fix somewhere in PATH that does exec ..../python ..../pipx.pyz

[chrysle]

Where should the zipapp be stored? And it must be updated by hand, this should probably be included in the script fix.

Also, I don't think it should be suggested to tweak the PATH (if that is what you want).

[uranusjr]

It can be added to ~/.local/bin. pipx ensurepath would add that to PATH.

[chrysle]

Do you think of a script approach like in #849 ?

[dukecat0]

Maybe we can merge this PR first, and leave all these works in the follow-up PRs? :)

[koterpillar]

FYI, pipx.pyz contains a shellbang header so it can be made executable directly.
