Common problem for novice mercurial users is not getting “fingerprints” for their HTTPS repository servers.

It’s usually recognized by getting next error when trying to push/pull from protected HTTPS repository:

abort: error: _ssl.c:507: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

To fix this issue just get a SHA fingerprint and store it in your configuration file.

Windows systems

For GUI configuration (here example from TortoiseHG).

• Press View>Syncronize.

• Make sure you have https in protocol selection box. Then press yellow lock button

• Now select “Verify with stored host fingerprint (good)” and press Query to retrieve and save server SHA fingerprint.

• Ensure correct username and password in User Authentication fields.

• Save settings.

Alternative way, manual configuration edit mercurial.ini configuration file.

[hostfingerprints]

dev.xdevs.com = 9d:d7:a7:37:47:f1:86:52:a4:05:1b:47:23:ce:1e:3d:6f:60:a4:f0


	
[auth]

dev.xdevs.com.prefix = dev.xdevs.com

dev.xdevs.com.username = your_username_here

dev.xdevs.com.password = your_password_here

Now push and pull operations should be working just fine.
