apt-cyg should check if required executables are provided by cygwin itself

[wrobelda]

I have GnuPG installed in C:\Program Files which is picked up by apt-cyg if gnupg is not available from within cygwin. This causes apt-cyg to fail, since the external gpg.exe is not aware of cygwin's System V folder structure.

apt-cyg should check during the initial check whether the tools required are provided by cygwin itself.

Hmm,,,
Why do you avoid to install gnupg on cygwin?
I think that is important to verify signatures for security.
Thus, I strongly recommend to install gnupg on cygwin, if you want to use apt-cyg of my fork.

But, my fork provides -X option for peoples who temporary can't use gnupg on cygwin or who don't want to use gnupg on cygwin.
My suggestion for such peoples is below:

alias apt-cyg='apt-cyg -X'

But, it is not a good idea for security.

Proabably because the Cygwin packages of gnupg always used to be outdated or dysfunctional.

Is it outdated, really?

Current version of GnuPG seems:

Name	Version	Date
GnuPG	2.2.10	2018-08-30
GnuPG 1.4	1.4.23	2018-06-11

See: https://gnupg.org/download/

And current gnupg package of cygwin is:

$ apt-cyg download gnupg gnupg2
$ ls -lgo --time-style="+%F %T"
-rw-r--r-- 1 1147816 2018-08-03 23:58:46 gnupg-1.4.23-1.tar.xz
-rw-r--r-- 1 2365240 2018-08-31 00:32:06 gnupg2-2.2.10-1.tar.xz

It seems up to date.

Yep, now it is, but a 6 months ago it wasn't.

I think you can close this issue.

Hmm,,,
This issue relates to issue #41.
Windows 10 1803 has win32 native tar and curl, but it doesn't have wget at this time.
