Please report + this problem to the public mailing list cygwin@cygwin.com + Recent Cygwin releases changed this to the message: + + This typically occurs if you're using an older Cygwin version on a newer Windows. + Please update to the latest available Cygwin version from https://cygwin.com/. + If the problem persists, please see https://cygwin.com/problems.html. + This is not serious, just a warning that Cygwin may not always be + able to exactly emulate all aspects of Unix current directory handling + under your Windows release. + Unfortunately some projects and products still distribute older + Cygwin releases which may not fully support newer Windows releases, + instead of installing the current release from the Cygwin project. + They also may not provide any obvious way to keep the Cygwin packages + their application uses up to date with fixes for security issues and + upgrades. + The solution is simply downloading and running Cygwin Setup, + following the instructions in the Internet Setup section of + + Setting Up Cygwin in the Cygwin User's Guide. + Please exit from all applications before running Cygwin Setup. + When running Setup, you should not change most of the values presented, + just select the Next button in most cases, as you + already have a Cygwin release installed, and only want to upgrade your + current installation. + You should make your own selection if the internet connection to your + system requires a proxy; and you must always pick an up to date Cygwin + download (mirror) site, preferably the site nearest to your system for + faster downloads, as shown, with more details to help you choose, on the + + Mirror Sites web page. + Cygwin Setup will download and apply upgrades to all packages + required for Cygwin itself and installed applications. + Any problems with applying updates, or the application after updates, + should be reported to the project or product supplier for remedial + action. + As Cygwin is a volunteer project, unable to provide support for older + releases installed by projects or products, it would be helpful to let + other users know what project or product you installed, in a quick + + email. + +
