pip disappeared after system upgrade
I upgraded from 22.10 to 23.04 just now without any problems. However, after the upgrade my pip is not working and I cannot figure out how to make it working again.
If i just want to call it:
pip
bash: /usr/local/bin/pip: cannot execute: required file not found
With sudo:
sudo pip
sudo: unable to execute /usr/local/bin/pip: No such file or directory
The executables are seemingly there:
ls -la /usr/local/bin/pip*
-rwxr-xr-x 1 root root 224 febr 21 12:13 /usr/local/bin/pip
-rwxr-xr-x 1 root root 224 febr 21 12:13 /usr/local/bin/pip3
-rwxr-xr-x 1 root root 224 febr 21 12:13 /usr/local/bin/pip3.10
If I call it within python (w conda):
python3 -m pip
/home/gerdos/miniconda3/bin/python3: No module named pip.__main__; 'pip' is a package and cannot be directly executed
Without conda it seems to work, but acting strange:
python3 -m pip install --upgrade pip
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
I already tried to remove and install pip with apt, but it did not help.
sudo apt remove python-pip
sudo apt install python-pip
I use python 90% of the time I use my laptop, it would be essential for me to make pip and conda work properly. I have absolutely no idea what is going on.
So I found this answer: https://stackoverflow.com/questions/75602063/pip-install-r-requirements-txt-is-failing-this-environment-is-externally-manag
I understand the error: externally-managed-environment, however the rest of the question still stands. I guess my conda is broken?
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
sudo apt install python3-pip
First install pipx:
$ sudo apt install pipx
and then use it like this:
$ pipx install yt-dlp
$ pipx upgrade-all
Note that you should use pipx for installing Python packages under your "normal" user and not system-wide. Never use sudo pip ... or sudo pipx ...!

From https://pypa.github.io/pipx/:
pip is a general-purpose package installer for both libraries and apps with no environment isolation. pipx is made specifically for application installation, as it adds isolation yet still makes the apps available in your shell: pipx creates an isolated environment for each application and its associated packages.
FWIW, on Ubuntu 20.04 I have been using
$ python3 -m pip --help
...
$ python3 -m pip install --upgrade pip
