Error in Updater

Support

Got it - I have an Ubuntu VM sitting around, I’ll see if I can replicate the problem.

Just out of curiosity is it actually working OK even though it’s logging that error?

And to what destination type are you pointing (S3, SFTP, WebDAV, etc.)?

My uneducated GUESS is that the issue is related to certificates. Windows ships with a bunch of Root and Intermediate Certificate Authorities (CA) which I believe are kept fresh with Windows Update.

Unfortunately, it appears Mono’s certificate store is empty by default. This page (FAQ: Security | Mono) suggests four solutions, 3 of which are potentially useful:

  1. Make sure ca-certificates-mono is installed (if you’ve got Mono 3.12.0 or newer)
  2. Use the Mono certmgr.exe tool to add root certificates into the Mono Trust store
  3. use the Mono 1.1.10+ mozroots.exe tool to download and install ALL off Mozilla’s root certificates
