Question: After VScode installation, when I tried to open my integrated terminal window, each time I am getting error mentioned in the title.

I don't know what is the correct path to shell-executable. Before VSCode installation, the only change I done in terminal is I installed zsh in it.

System Details -

* OS: Ubuntu 20.04 LTS
* VSCode version: 1.53.2

Answer: 
I solved this issue by changing by default shell for vs-code with following steps:

1. Open settings-search in VSCode with `Cntr + Shift + p`
2. Search for `default`
3. clicked `Terminal: Select Default Shell`
4. clicked `zsh /usr/bin/zsh`, I selected zsh as I recently installed it and like to use it, you can use other terminal options as well.

Thank you.
The option "terminal.integrated.shell.linux" is deprecated.

The new VSCode config is (mine is 1.62.3 on Ubuntu):

```
    "terminal.integrated.defaultProfile.linux": "zsh",
    "terminal.integrated.profiles.linux": {
        "zsh": {
            "path": "/usr/bin/zsh",
        }
    },

```

If only "terminal.integrated.defaultProfile." is set, it can not find zsh.
