This is the easy part, but how do I install a package via bash?
I tried it this way:


W10dev:/usr/local: /setup-x86_64.exe  -M -B -R "$CYGWIN_ROOT" -l "$CYGWIN_ROOT/.pkg-cache" -s https://ftp.fau.de/cygwin -P mksh
Starting cygwin install, version 2.908
User has NO backup/restore rights
io_stream_cygfile: fopen(/etc/setup/setup.rc) failed 2 No such file or directory
Current Directory: C:\Users\admin\cygwin/.pkg-cache
root: C:\Users\admin\cygwin user
Selected local directory: C:\Users\admin\cygwin/.pkg-cache
net: Preconfig
site: https://ftp.fau.de/cygwin/


But got "Nothing to install or update"

The fopen() error is mysterious for me, too:

W10dev:/usr/local: ll /etc/setup/setup.rc
-rw-r--r-- admin None 11,850 2021-07-08 15:36:54 /etc/setup/setup.rc

W10dev:/usr/local: head -2 /etc/setup/setup.rc

        C:\Users\admin\cygwin/.pkg-cache
