Thunderbird 60 gcontactsync Blocked after enabling OAuth2

19/12/2020 by James

These notes apply to Kubuntu 18.04 and Thunderbird 60.9.1.

After Google restricted access for LSA’s (Less Secure Apps) it was necessary to change the Gmail account authentication method from “Normal Password” to OAuth2. After this gcontactsync failed – after logging into Google and successfully allowing access to Contacts it was blocked. After extensively trawling the net for a solution one was found. This said the problem was due to Thunderbird being corrupted and the solution offered was a complete rebuild – drastic but it worked!
