Sometimes when you work on a repository you may have commited a change locally that is not pushed to the remote branch. As git is a collaborative platform other people may have commited in your branch and you may need to perform a git pull in order to get the latest changes.
Lets examine a common scenario on which you left behind your local branch. By executing git status we see that one commit that is performed on the local copy is not pushed.
The latest commit in the remote is the one with hash d82186bf6fbfdc8bb38ab5bd12b4bc170b550b7c
However the latest commit in the local repository (not in the same version as the remote) is the one shown below with the hash cd4a8c6f336fa5f7afad7d7d53d2555b7c87aabe and cannot be pulled because there are conflicts with my local commits.
When you have such conflicts you should define what you need to do. In my case I wanted to abort my local commit and get the latest version of the repository.
In order to do so
git reset --hard origin/main
Then by getting the status and pulling you will verify that the latest commit is the one that is the most recent on the repository and your local changes have been discarded.
