Canvas Upgrade

[Kumar1]

Hi,

I was trying to upgrade canvas on my AWS Instance, but I was not able to get the canvas application up and running and got this error:

/usr/local/lib/site_ruby/2.6.0/rubygems/dependency.rb:311:in `to_specs': Could not find 'racc' (~> 1.4) among 364 total gem(s)
(Gem::MissingSpecError)
Checked in 'GEM_PATH=/var/canvas/vendor/bundle/ruby/2.6.0', execute `gem env` for more information

Can anyone please look into it?
