The messages say it all: "self signed certificate in certificate chain".
The TLS connection is not trustworthy, because any network transport participant is intercepting encrypted data traffic by decrypting and re-encrypting it using an unverified self-signed certificate.
This may have following reasons:
- you are using a SSL proxy
- any bad configured network security (antivirus) appliance is involved
- you are victim of a man-in-the-middle attack
In case you are connecting to internet through a (known and trusted) SSL proxy or security appliance, you can add its public certificate to PC's trust store to solve the problem by...
-
opening Command Palette
-
calling Package Control: User CA bundle
-
pasting public key to the opened file and safe it.
The content should look like
-----BEGIN CERTIFICATE----- MIIEejCCA2KgAwIBAgIICKHBJ8mrnl8wDQYJKoZIhvcNAQELBQAwgdoxCzAJBgNV ... -----END CERTIFICATE-----
Note: Those steps work only for urllib
downloader. Any other downloader, especially wininet
requires certificates to be installed to OS's native certificate trust store.
Package Control verifies the whole certificate chain for any server it connects to in order to avoid anyone injecting malware. This is not and won't be configurable.
You have to ensure a trustworthy connection can be established.
