这个问题是关于离线地图的，但在给定的机会下，我想要资源来了解更多关于 ssl 证书以及与它们的整个交易。
我下载了最新的离线地图 (7.0.6)，在完成最小配置后，我运行命令，但出现以下错误：
Account sync Gmail:
*** Processing account Gmail

ERROR: No CA certificates and no server fingerprints configured. You must configure at least something, otherwise having SSL helps nothing.
*** Finished account 'Gmail' in 0:00
ERROR: Exceptions occurred during the run!
