ubuntu vi arrow keys, delete key problem

Ubuntu vi direction keys, delete key problem:


After reinstalling the ubuntu system in the past two days, I found that when using VI, the arrow keys turned into ABCD after pressing down, and the delete key was invalid. After searching on the Internet, it should be the problem of the VI software itself. Just uninstall and reinstall. The steps are as follows:

    1. Execute the command sudo apt-get remove vim-common

    2. Execute the command sudo apt-get install vim



    OK, the VI returns to normal .
