Today, in Git push origin master, the error “unable to read ask pass response from ‘/ usr / libexec / openssh / Gnome SSH ask pass
appears

Search out the following paragraph. Let SSH_ Askpass can be turned off.

However, for some wierd reason, upon trying to pull/push commits from/to the Git repository, the bash shell tries to open the gnome-ssh-askpass dialogue and it fails. I wanted to prevent the bash shell from attempting to launch the dialogue box. To do this, all I had to do is run the following command in the terminal:
$ unset SSH_ ASKPASS

To prevent it in future, you can add the above line in your .bashrc or .bash_ profile.

Wish you trouble-free working!
