Mv menlo.font menlo.otf not working

Sorry for your troubles @KeshavMaheshwari. There’s a number of troubleshooting steps you can try here. It sounds like you tried the thing I would suggest. Reset + exit and restart terminal. I would maybe try those again. I have seen other people say it didn’t work for them on the first try.

I really don’t know what else to try. There is a last resort option in the troubleshooting to start from the beginning again. I bet you could catch back up to where you got stuck pretty quickly.
