I can’t update WP Core or plugins on my Local sites.

Updating core from WP Admin UI generates:

Download failed.: cURL error 35: Unknown SSL protocol error in connection to downloads.wordpress.org:443

Updating from the WP Admin UI plugins generate:

An error occurred while updating iThemes Sync: Download failed. cURL error 35: Unknown SSL protocol error in connection to downloads.wordpress.org:443

WP CLI:

@ColinD,

Can you please try the following?

  1. Right-click on the site in Local’s sidebar and go to “Open Site SSH”
  2. Run apt-get update && apt-get install ca-certificates
