The ca-certificates-letsencrypt package will be obsoleted as soon as certificates (or libraries / applications) that need the workaround cease to exist in the wild. I think the maximum lifetime of client certificates is 60 days, but the intermediate cert validity using the cross-signed chain that triggers this problem is much longer than that (for compatibility with older Android versions).

I'll report back with the result. This did the trick. Regarding the outdated version of GnuTLS available in Cygwin, I see that these trust anchor changes constitute a workaround. Furthermore, I see that ca-certificates-2.50-4 and ca-certificates-letsencrypt-2.50-4 were released, which automate the above quoted process. Very nice! My final question would be if ca-certificates-letsencrypt will eventually be merged into ca-certificates? I am now happily browsing the web again in Cygwin Emacs. Thank you to this mailing list and those in IRC who helped me debug the problem. I learned a lot about certificate trust chains in the process! -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
Re: Emacs, GnuTLS, and DST Root CA X3
I followed the recent announcements, but unfortunately the problem persists. I tested on two computers, with the following ca-certificates versions: - ca-certificates-2.40-1 - ca-certificates-2.50-1 - ca-certificates-2.50-2 - ca-certificates-2.50-3 - ca-certificates-2.50-3 AND ca-certificates-letsencrypt-2.50-3 In all cases, the result was the same. >From the ca-certificates-letsencrypt-2.50-3 announcement: > It may be necessary to also remove trust for the already expired DST > X3 root CA I'm still trying to figure out _how_ to do this, although I'm not sure whether it should help my situation. I'll report back with the result. Some (non-Cygwin) Emacs users reported that GnuTLS >= 3.6.14 works. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
