-Known Problem
-------------
-
-### 2016-02-12: Problems about the ACL
-
-In recent version, the cygwin changed the ACL mechanism .
-So, in the cygwin current version, if it will be installed by `setup.exe` with `-B` or `--no-admin` option,
-the cygwin root (/) does not have correct ACL.
-
-A new subcommand `repair-acl` tries to repair it.
-But some package, that are failed to install by the ACL problem, need to be reinstalled.
-
-
-
-### 2015-04-09: gpgv seems not work correctly on 32 bit environment
-
-To solve this problem, the backend of `verify_signatures` function was changed from `gpgv` to `gpg`.
-thienhv reported this problem [#14](https://github.com/kou1okada/apt-cyg/issues/14). Thanks.
-
-### 2014-01-17: ca-certificates package is not setup correct at x86_64 with Windows 8.
-
-After clean installing with `setup-x86_64.exe`, there are something wrong about ca-certificate package as below:
-
-    $ ls -lnG \
-         /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
-         /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-    -r--r--r-- 1 1001 314336 Jan 17 18:17 /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-    -rw-r--r-- 1 1001      0 Oct 16 12:35 /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-    $ ls -lnG \
-         /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
-         /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-    -r--r--r-- 1 1001 232342 Jan 17 18:17 /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-    -rw-r--r-- 1 1001      0 Oct 16 12:35 /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-
-The x86 environment seems no problem except that need an additional setting for wget and ca-certificate. Hmm,,,    
-
-It seems that `/usr/bin/update-ca-trust` is failed at x86_64.
-
-It's ad hoc, but effective way to fix it, is to copy files from cygwin32 to cygwin64, as below:
-
-    cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt \
-          /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-    cp -a /cygdrive/c/cygwin/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem \
-          /cygdrive/c/cygwin64/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-
-This problem is fixed at 2014-01-24.
-version 0.18.7-1 of p11-kit, p11-kit-trust and libp11-kit0 did not work at the cygwin64 under the Windows 8.
-If you face the above problem, please upgrade these three packages from version 0.18.7-1 to version 0.18.7-2.

-### 2014-01-15: Signature check failed at cygwinports x86_64.

-    You can use the `bzip2recover' program to attempt to recover

-
-As of 2014-01-24, above problem is recovered at least.
-
-### FIXED: Check setup (`cygcheck -c`) can not detect .tar.xz packages
-
-At cygwin 1.7.25, cygcheck is hardcoded for .tar.gz and .tar.bz2.
-So check setup (`cygcheck -c`) can not detect .tar.xz packages.
-This bug was already fixed with [src/winsup/utils/dump_setup.cc#rev1.28](http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/utils/dump_setup.cc?cvsroot=src#rev1.28).
-Please wait a release of cygwin 1.7.26.
-
-This Problem was fixed [cygwin 1.7.26](http://cygwin.com/ml/cygwin-announce/2013-11/msg00027.html) which released at 2013-11-29.
