cygwin setup version 2.909 not installing (silent mode) - bug or user error?

If the last execution of the setup used download only and the setup is used with -q and without either -D or -L it still defaults to -D


Adding -Y does not change the behavior either.


Workaround was to launch setup, advance to “select download source”, select install, advance to next screen, abort, re-run silent install.


>From setup --help:

-D --download                     Download packages from internet only

-L --local-install                Install packages from local directory only

-Y --prune-install                Prune the installation to only the requested




full command used:


$ ./profile/Downloads/setup-x86_64.exe -R 'c:\cygwin.postfix' -X -B -d -n -r -N -q -l 'C:\cygwin64\tmp\mirror' -f -o -P 'openssl-devel,libpq-devel,libmysqlclient-devel,libsqlite3-devel,openldap-devel,libpcre-devel,libdb-devel,libpq5,cygport' -s ''
