Email client did something unexpected with line breaks. I've loopback tested this resend first. Getting consistent permission denied errors on postinstall of ca-certificate.

This is caused by p11-kit removing write permissions even for the user from the hash directory when it is finished. This went unnoticed for essentially forever (the commit doing this is over 10 years old), most likely since an admin on Windows will be able to write a new directory entry anyway by way of SeRestorePrivilege and similarly root on UNIX system can still create new files in such directories (unless a suitably restricted SELinux policy is active). > I've experienced this on two installs, both where I run setup exe with > -B, no privelege elevation). Both installs have had an manual > manipulation of the directory, or its parents up to /etc. See above. And since it's p11-kit doing this, just patching up the postinstall script to change permissions won't do, as update-ca-trust will run p11-kit by itself before it tries to create the symlink.

I ran the script as follows: 1. Started cmd.exe 2. set PATH=C:\<path-to-cygwin-installation>\bin;%PATH% 3. C:\<path-to-cygwin-installation>\bin\bash.exe --norc --noprofile "/etc/postinstall/ca-certificates.sh" Step 3 is one line and was logged by the setup program before it reported "abnormal exit: exit code=1" Sorry, I cannot tell anything about ca-certificates-letsencrypt.sh as the corresponding package has not been installed.
