I was rebuilding with ./launcher rebuild myapp and got following error :

Which release are you on? Stable, Beta or tests-passed?

3

stable

When go to discourse web it shows me : discourse v2.3.6

4

Looks like @gerhard fixed this 10 days ago, there were some 6.0 migrations which caused issues with stable.

Run a:

git pull
./launcher rebuild app

Or if you renamed your app.yml as myapp.yml ./launcher rebuild myapp

Then try again- report back if it doesn’t work.

Yes I did it couple of times.
It is not working

I fixed the migration in the akismet plugin. Please give it a try by rebuilding your app.
