Apt cyg error updating setup ini
Run setup-x86_64any time you want to update or install a Cygwin package for 64-bit windows.
The signature for setup-x86_64can be used to verify the validity of this binary using this public key.
Don't worry if you have a 64-bit machine, a 32-bit Magic Lantern development environment works better than a 64-bit Cygwin installation.
Once you've installed your desired subset of the Cygwin distribution, setup*will remember what you selected so rerunning the program will update your system with any new package releases.
Additionally, Windows does not easily allow overwriting of in-use executables so installing a new version of the Cygwin DLL while a package manager is using the DLL is problematic. This will install an enormous amount of packages that you will never use, including debuginfo and source for every package.
