recently I rebooted my laptop and I get the below message when I try to run the node.

Any idea what I should do? I installed the latest PPA binaries.

The release notes for 7.5+ contain instructions for getting rust built and the Zcash stuff. Make sure to check them out on the Gitlab.

Here’s the rust info http://tezos.gitlab.io/introduction/howtoget.html#setup-rust


OK - got it: wget https://raw.githubusercontent.com/zcash/zcash/master/zcutil/fetch-params.sh chmod +x fetch-params.sh ./fetch-params.sh

Any ideas what these params are for?

PS: happy this works because building from scratch didn't work anymore (rust missing)
