Unable to Install OS X El Capitan FileVault conversion in progress

I am trying to upgrade to El Capitan and a message pops up saying the following:

FileVault conversion in progress.

Use the "Security and Privacy" preference pane to check conversion status.


I had this problem from Yosemite since I bought a new MacBook Pro and left the default value for an encrypted volume on.


I have tried every solution I could find without being able to solve the problem or downgrade to an unencrypted version without sucess.


I could use your help as this issue now affect my ability to install the new MacOS.


Thanks in advance.

MacBook Pro with Retina display, OS X Yosemite (10.10.5), 15-inch, Mid 2014

Dude, you saved my ***! This worked! Thanks so much!


I was trying to install Sierra but the File Vault screwed things up and was paused just as described here, which completely blocked me. I could not even login to turn File Vault off! I followed all instructions exactly, and your solution worked. The only difference for me was that after the file conversion process had been completed, there was also an "optimization" process that then started after conversion had been completed. Rather than interrupt this, I opted to let it finish--which took about 2 hours! Once optimization was done, I was then able to use disk utilities to install a new OS, which turned out just to be the Sierra download that started all the hardships. All data was saved, nothing was lost, no settings changed. Phew! What a relief! Thanks so much!!!
