Fixing "fatal: unable to find remote helper for 'https'" on Ubuntu

Hey there, let's sort out that annoying error you're hitting when trying to clone a GitHub repo on Ubuntu. First off, quick check: you wrote github clone in your question, but the correct command is git clone — that's a super common typo, so make sure you're using the right one first. If you already fixed that, let's dive into the real fixes:

Solution 1: Reinstall Git with HTTPS dependencies

This error almost always happens because Git is missing the libraries it needs to handle HTTPS connections. Here's how to fix that:

First, update your package list to make sure you're grabbing the latest versions:
```
sudo apt update
```
Install all the required curl and SSL libraries that enable HTTPS support in Git:
```
sudo apt install libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev
```
Now, completely remove and reinstall Git to ensure it picks up these new dependencies:
```
sudo apt remove --purge git
sudo apt install git
```
Once that's done, test your clone command again:
```
git clone "https://your-repo-link-here"
```

Solution 2: Verify Git's remote helper files

Sometimes the git-remote-https binary (the file that handles HTTPS connections for Git) goes missing or ends up in the wrong spot. Let's check:

First, find where Git stores its executable files:
```
git --exec-path
```
You'll get a path like /usr/lib/git-core. Now check if the HTTPS helper exists there:
```
ls $(git --exec-path) | grep git-remote-https
```
If you don't see git-remote-https in the output, re-installing Git (like in Solution 1) should bring it back. If you compiled Git yourself, you might need to recompile it with HTTPS support enabled.

Solution 3: Compile Git from source (for stubborn cases)

If the apt-installed Git still isn't working, compiling from source lets you explicitly enable HTTPS support. Here's how:

Install all the tools needed to build Git from scratch:

sudo apt install build-essential libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev

Grab the latest stable Git release (you can check the latest version number on the Git website, but 2.45.1 is a solid choice right now):
```
wget https://www.kernel.org/pub/software/scm/git/git-2.45.1.tar.gz
tar -xf git-2.45.1.tar.gz
cd git-2.45.1
```

Configure the build to include HTTPS support:

./configure --prefix=/usr/local --with-curl

Compile and install Git:
```
make
sudo make install
```
Double-check the installation worked:
```
git --version
```
Now try cloning your repo again — this should do the trick.

Solution 4: Check your PATH variable

Occasionally, Git's executable path isn't properly added to your system's PATH, which can break remote helpers. Let's verify:

Run this to see your current PATH:
```
echo $PATH
```
Make sure the path from git --exec-path (from Solution 2) is listed here. If not, add it temporarily with:
```
export PATH=$PATH:$(git --exec-path)
```
To make this permanent, edit your shell config file (like ~/.bashrc for Bash or ~/.zshrc for Zsh), add that line at the end, then restart your terminal.
