While working on PSWriteExcel on Ubuntu / Mac OS I've noticed that my -AutoFit method for ConvertTo-Excel was crashing. I couldn't reproduce same behavior on PowerShell Core on Windows so it must be something with how Ubuntu / Mac OS deals with it. The error I was getting:
Failed AutoFit with error message: Exception calling „AutoFitColumns” with „0” argument(s): „The type initializer for 'Gdip' threw an exception.”
It seems the issue is known and reported on GitHub. Until then… you need to work with workaround as below..
To fix this you need to run following commands and install or update libgdiplus.
apt install -y libc6-dev apt install -y libgdiplus
On Mac OS it's a almost the same with the difference of using brew
brew install mono-libgdiplus
After this little update.. no more errors
If you're working with Azure DevOps change required to Mac OS looks like this (surprisingly Ubuntu doesn't have this error)

If you're working with Travis updated .travis.yml looks like this which covers both Ubuntu and Mac OS
