Error: homebrew/dupes was deprecated

[paulprovost]

Upgrading on Ubuntu 16.04 LTS (ruby 2.3.1p112) shows:

Error: homebrew/dupes was deprecated. This tap is now empty as all its formulae were migrated.

How do I fix this?

Hi, Paul.

brew untap homebrew/dupes

Homebrew/dupes is no longer needed.

[paulprovost]

Hi Shaun,

Yeah, I tried that, but I got

Error: No available tap homebrew/dupes.

Sorry, I should have said that up front...

[sjackman]

My best guess is that you have another tap tapped that refers to a formula in Homebrew/dupes. Try…

grep -irl homebrew/dupes $(brew --repo homebrew/core)/../..

[paulprovost]

/home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-core/../../homebrew/homebrew-core/Formula/lsh.rb

So

brew untap lsh

?

[sjackman]

My copy of lsh.rb does not mention homebrew/dupes, so brew update should resolve this issue. If it doesn't, please report brew config

It seems to be related to gpgme, which notmuchdepends on.

brew update does not fix it. Here's brew config:

This looks fine.

/home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-core/../../homebrew/homebrew-core/Formula/lsh.rb

I'd suggest removing this file, and any other file that mentions homebrew/dupes and then run brew update.

[sjackman]

You could also try rm -rf /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-core and then brew update.

[paulprovost]

Tried both, to no avail.

[sjackman]

What's the output now of…

grep -irl homebrew/dupes $(brew --repo homebrew/core)/../..

[sjackman]

lsh is a red herring. That hit comes from this comment:
