"No formulae or casks found for..."

[spikedout]

Hello, so after force deleting a cask, in particular 'nextcloud' one, and also after manually deleting some related to that particular cask files, I get basically that it's not found in repositories.
So, how do I fix this?

OS: macOS Catalina
brew version: 3.4.1-56-gf767293

Thanks in advance.

What did you do to delete it and what are you running when you get that message?

[gromgit]

Then what's the output of the following commands?

brew config
brew doctor
brew search nextcloud

brew search nextcloud

Error: No formulae or casks found for "nextcloud".

You've mangled your core and cask taps pretty badly. Do

rm -rf $(brew --repo homebrew/core)
rm -rf $(brew --repo homebrew/cask)
brew tap homebrew/core
brew tap homebrew/cask

[gromgit]

The brew doctor output shows your problem in graphic detail: You've messed up your core and cask taps with a ton of deletes (including the nextcloud cask, hence the error message you saw) and inserts. The most straightforward way to fix both is to re-tap them:

rm -fr $(brew --repo homebrew/core)
brew tap homebrew/core
brew untap --force homebrew/cask
brew tap homebrew/cask

@gromgit I have successfully applied your's suggested commands and seems that everything's good. I have successfully searched and installed the nextcloud cask.
Very big thanks to everyone who got in touch with me and helped with this issue!
Wish you guys nothing but the best!
