Are your Cygwin and ssh servers allowed or supported by your sysadmins? Could they have changed some protection settings or policies to block the programs or connections on Saturday? Are your hosts running antivirus and could they have been changed or upgraded Saturday? See BLODA: https://cygwin.com/faq/faq.html#faq.using.bloda Are your hosts running Cygwin or Windows SSH servers? Check that they are not trying to run both, or running only Windows SSH, that your system and servicea startup ensures that, and did not change Saturday! Check your firewall rules did not change Saturday to drop allowing incoming ssh connections or make other changes to them. > With heavily automated infrastructure, the automation scripts are breaking > currently. > > Even from the localhost, when we open the cygwin terminal type exit, it is > not closing the console > > Tried reinstalling Cygwin but the install process hangs forever on > ca-certificate post installation. Try running sh -vx /etc/postinstall/ca-certificates.sh to see if and where it is getting stuck. Also sh -vx /etc/postinstall/ca-certificates-letsencrypt.sh if you are allowing letsencrypt certs. If you are using any additional external or internal CAs or certs, check that they are still installed and working. This all assumes you are running current Cygwin and ssh packages. In any case it is useful to follow the Cygwin problem reporting guidelines appended to each post below, by replying to the list with a copy of the output from running `cygcheck -hrsv > cygcheck-hrsv.log` on a failing system attached as text, with any other relevant details of your Windows systems. -- Take care.
