pyenv Python 3.11.5 install fails in Kubuntu 23.04

I'm using zsh and oh-my-zsh. I'm doing

➜  ~ pyenv install 3.11.5

and the output is:

I saw a bunch of answers that say python must be aliased somewhere, but I did not do that. Here's what's in my .zshrc file:

export ZSH="$HOME/.oh-my-zsh"
plugins=(git)

source $ZSH/oh-my-zsh.sh

# pyenv
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv virtualenv-init -)"

# alias nvim
alias vi="nvim"

As for the various oh-my-zsh config files, they all have the default options as far as I know. I did not personally change anything.

I should also add that:
