[Bug 2017806] Re: do-release-upgrade can not use apt socks5h proxy settings.

[Changbin Du]

First, enable debug logs:
$ DEBUG_UPDATE_MANAGER=1 do-release-upgrade
...
result of meta-release download: '<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)>'
...

So in my case, the connection failed due to the certification of the
proxy. Then change /usr/bin/do-release-upgrade to ignore this check.
Insert this code at the beginning of /usr/bin/do-release-upgrade file
but after the '__future__' line:


from __future__ import print_function

import ssl
try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    pass
else:
    ssl._create_default_https_context = _create_unverified_https_context


ok, now it works!
