Crash on Linux: Paket failed with -> Win32Exception: An error occurred trying to start process 'dotnet' with working directory '/home/knocte/Documents/FSharpLint'. No such file or directory

Description

Trying to run `~/.dotnet/tools/paket update Ionide.ProjInfo.ProjectSystem resulted in the error:

Paket failed with
-> Win32Exception: An error occurred trying to start process 'dotnet' with working directory '/home/knocte/Documents/FSharpLint'. No such file or directory

Repro steps

1. Install ubuntu 20.04

2. Install dotnet via curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin as instructed by https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script

3. Do export DOTNET_ROOT=$HOME/.dotnet as instructed by https://github.com/fsprojects/fantomas/issues/412#issuecomment-798774514

4. Do export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 as instructed by https://docs.microsoft.com/en-us/dotnet/core/runtime-config/globalization

5. Install paket via ~/.dotnet/dotnet tool update -g paket.

6. Clone git@github.com:fsprojects/FSharpLint.git (at the time of writing, master branch is at commit hash 2688e50bfdf7b0344eb3404d1c232b09ad90bfa1 )

7. cd FSharpLint and run paket restore via ~/.dotnet/tools/paket restore (it works, dependencies are restored)

8. Run ~/.dotnet/tools/paket update Ionide.ProjInfo.ProjectSystem

Expected behavior

Should upgrade paket.dependencies file to raise Ionide.ProjInfo.ProjectSystem's version to latest.

Actual behavior

Crashes:

$ ~/.dotnet/tools/paket update Ionide.ProjInfo.ProjectSystem

Known workarounds

Not yet.

Reproduce the failure from an FSharpLint checkout with ~/.dotnet/tools/paket update Ionide.ProjInfo.ProjectSystem, then examine the paket.dependencies update flow and the FSharpLint.sln restore step. Done means the command completes on Ubuntu 20.04 without failing to start dotnet from the project directory and updates the requested dependency.
