Originally created by @carlosvsilva on GitHub (Nov 13, 2020).

Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd]: Microsoft Windows [Version 10.0.19042.630]
Windows Terminal version (if applicable): 1.4.3141.0

Any other software?

vim 2:8.0.1453-1ubuntu1.4
Ubuntu 18.04

Steps to reproduce

In Windows Terminal, from a Ubuntu 18.04.5 LTS shell with all latest updates applied, I ssh to my Windows 10 20H2 (10.0.19042.630) with latest native Microsoft OpenSSH installed and start the session in a WSL2 Ubuntu 18.04.5 LTS with all latest updates applied. I then vi a terraform textfile in vim 2:8.0.1453-1ubuntu1.4 and as soon as I press the down arrow key to navigate the document, vi goes into Insert mode an deletes some lines all at once.

Expected behavior

I expect to navigate the text document normally and have the cursor go down a line every time I press the down arrow like when I do the same action from a cmd.exe terminal/native Ubuntu WSL2 terminal in Windows.

Actual behavior

Pressing the down arrow key deletes some lines and enters insert mode in vim instead of navigating normally.

I believe that this is a /duplicate of #1637. OpenSSH uses the version of the Windows console that comes with the OS, which means it'll be a little slower to update. Sorry about that!

The workaround doesn't work for me:
Workaround: Adding set t_u7= or set ambw=double to your vimrc should fix the problem

Isn't this about Windows Terminal itself, since from cmd.exe nothing wrong seems to happen? Thanks

Hmm. Have to think about this a little more.

It seems that wsl2 does not work even with build 20H2 19042.630, I just updated my windows to that version and I can't install wsl2 and I don't know why.

Sorry that WSL2 stopped working for you. I hope that you got it sorted out.

What version of Windows is running on the SSH server?

The SSH server is running Microsoft Windows [Version 10.0.19042.630]. Basically Windows 10 20H2 all up to date. Thanks

Okay, I hit this every day as well. Vim deletes a huge chunk of my file.

This is a definite /duplicate of #1637, but I cannot explain why the workaround doesn't help. I'm sorry about that.
