I'm missing the python3 binary in /usr/bin/.

which python3 outputs /home/d4rkc10ud/anaconda3/bin/python3

sudo apt install python3 outputs python3 is already the newest version (3.12.3-0ubuntu1).

sudo apt install python3-dev outputs python3-dev is already the newest version (3.12.3-0ubuntu1).

A python3 file exists in /usr/local/bin that links to a python3.12 file in the same directory.

I'm running Kubuntu 24.04 on my machine. I'd really appreciate any help.

UPDATE:

file /usr/bin/python3 outputs /usr/bin/python3: broken symbolic link to python3.12

Maybe creating a symbolic link from /usr/bin/python3 to /usr/local/bin/python3.12 would help? I'm fairly new to linux so I'm afraid to just try it and mess things up more.

  • please don't start making such symlinks, out of guessing. Before you were using anaconda, did you manually install any python things system-wide, any other way than with apt? It's not usual that a python installation gets so messed up, so we're really left to wonder whether you'd have any idea what could have caused this. Commented Jul 31, 2024 at 9:03
  • for example, there really should not be a python3 in /usr/local – that points to your installing a non-packaged python. When did that happen? Commented Jul 31, 2024 at 9:04

You need to reinstall python3-minimal, after cleaning things up:

sudo rm -f /usr/bin/python3 /usr/bin/py3compile
sudo apt reinstall python3-minimal

Since the /usr/bin/python3 symlink is broken, you also need to reinstall python3.12-minimal:

sudo apt reinstall python3.12-minimal

    That returns the following error: E: Internal Error, No file name for python3-minimal:amd64 I tried running sudo apt install python3-minimal and that py3compile: not found. py3compile seems to depend on the missing #! /usr/bin/python3 file. Commented Jul 31, 2024 at 8:12
  • @MedhanshGarg this sounds a bit like you're running sudo apt… from within an conda environment. don't do that. Commented Jul 31, 2024 at 9:00
  • @MedhanshGarg you should remove the dangling symlink first, at least; see the updated answer. Commented Jul 31, 2024 at 9:32
  • I tried running the command outside the conda environment after running conda deactivate, still the same issues. I ran the rm command that you suggested. That seemed to remove the symlink and the py3compile file. I then ran the second command which threw an error saying E: Internal Error, No file name for python3-minimal:amd64. So I tried sudo apt install python3-minimal which seemed to run without any errors but it didn't seem to install python3. So I then retried the reinstall command which recreated the py3compile file and the broken symlink. Commented Jul 31, 2024 at 11:05
  • Should I try ./configure --prefix=/usr --enable-optimizations to install python from source into /usr/bin/? Commented Jul 31, 2024 at 11:23
