I get this error when I start zcashd: _Error: This version has been deprecated as of block height 239776. You should_ \_ upgrade to the latest version of Zcash. To disable deprecation for this version,\_ \_ set -disabledeprecation=1.0.11.\_ and I am wondering what should I do to update my zcash, I installed it on my ubuntu by following Debian package install instruction [Download Zcash | Zcash](https://z.cash/download.html) now should I just add set -disabledeprecation=1.0.11 in the zcash.conf, will this update my zcash client? ![Screenshot%20from%202018-03-11%2023-50-59](https://global.discourse-cdn.com/zcash/original/2X/e/e0afa6dc895bd08a275a2d99f44aa9e975df2955.png) ---

OK, Let me answer my own question, inspired by [Upgrading ZCash from 1.0.8 to 1.0.11](https://forum.zcashcommunity.com/t/upgrading-zcash-from-1-0-8-to-1-0-11/20864) because I’m new to Linux, this should be very easy for Linux users, simply do this two steps: apt-get update apt-get upgrade ,before doing this make sure your zcash stopped, zcashd-cli stop
