I just tried to use this release in a GitHub Action using the "dlang-community/setup-dlang@v1" action. I got an error about the signature is not trusted. I tried 2.092.0, that works fine. Here's the full output:

Thank you, Martin!

Thanks to everyone for this release.

I just upgraded a machine to Linux Mint 20 on a fresh install and tried to run the install script. It fails with
main: line 178: USERPROFILE: unbound variable

This line should only be called on Windows, which I found strange. It turns out that this is driven by

```
posix_terminal() {
    # If this script is run on Windows cmd by passing it as argument to bash.exe,
    # the shell level will be 1. If it is run from a POSIX terminal, it will be > 1.
    if [ "$SHLVL" = 1 ]; then
        false
    else
        true
    fi
}
```

Running `echo $SHLVL` prints `1`

Running
```
bash
echo $SHLVL
```
prints `2`


Running `echo $SHELL` prints `/bin/bash`

The issue seems to be related to an update to Ubuntu 16:

I don't think it is related to the Ubuntu 16.10 issue, because the above test does not rely on SHLVL being 2 initially. If the script is called from the terminal, and the terminal is running bash (which it seems to do according to the output of $SHELL) SHLVL should be at least 1 on the terminal and one higher when the script is run (since running a script starts a new bash). Maybe the script is run in a way that breaks this assumption? Is it run using `call`? Is it run headless, without a terminal? Is it not run by real bash?

There is a related conversation here, but not quite the same: https://github.com/dlang/installer/commit/e084815001390538bbd6fe5be7c2d4d81ee681b7#commitcomment-40487617

Please open an issue on https://issues.dlang.org/enter_bug.cgi and post a link here, if we need to drill deeper.

I can imagine that the current `posix_terminal()` is flawed if the terminal is running a shell that is not bash, for which we should find a solution.

Thanks for your reply. I have put some comments in line below.

Hmm, ok. So your point is that its ok for it to start out of SHLVL 1, but then it should be incremented by calling bash as part of the curl pipe and detected? Is there a simple example of this behavior I could test?

As far as I can tell it is real bash (from above, "Running `echo $SHELL` prints `/bin/bash`")...but I primarily use Windows.

All I did was install the operating system, update and restart as needed, open a terminal, and then went to the dlang downloads page and copy and pasted the line
curl -fsS https://dlang.org/install.sh | bash -s dmd
(I might have needed to make it sudo, I can't recall).

nexor specifically mentioned docker being a problem. After getting Linux Mint 20 set up and failing to use the install.sh script, I switched to the package on the website and it installed without issue. However, I later tried to get docker working and then ran into this issue again and was not able to use the same workaround (I know very little about docker and did not want to push my luck). So not being able to use docker seems like a bigger issue than not being able to use the install.sh on Linux Mint 20.

Thanks, I will look into this. I posted a workaround there, which involves separate steps for downloading the script and running the script.
