Have you tried to upgrade Magento from the command line (or some other way) and discovered the delicious error message:
Unknown cipher in list: TLSv1
Returned to you in your terminal window?
There is a fix which can work for this, below.
Edit the file downloader/lib/Mage/HTTP/Client/Curl.php, type the following command from the Magento installation directory:
Find the line
And replace it with the line
This should then perform as expected. Note, if you follow this with a Magento upgrade, you will need to complete this step next time, too… it will very likely be copied open. Cool.
Leave a comment below if this worked or didn’t work for you. Shout hooray or boo as appropriate.
