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:
