You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 4c8828d... Project snapshot

May be someone have any ideas what I'm doing wrong?

Answer 1

I tried several yarn + react-native-git-upgrade but it didn't work for me

To make the upgrade work I had to remove the node_modules and clean the yarn cache too.

1) Remove node_modules:

rm -rf ./node_modules

2) Clean yarn cache

rm -rf /Users/<myUsername>/Library/Caches/Yarn/v1/.tmp

yarn cache clean 

I am not sure if it would have worked with running just the removal of .tmp

3) Run yarn

4) Run upgrade again

react-native-git-upgrade

Note: My upgrade was from 0.51.0 to 0.53.3
