Emacs 30.1 breaks melpa package dependencies

[tensionhead]

This is probably more an emacs issue, but as I could not find anything on google about it I thought I at least report it here. So my working lsp-pyright environment suddenly broke after updating Emacs to 30.1 with the non-descript error:

Cannot load lsp-pyright

On the terminal I could see:

Unable to activate package ‘lsp-mode’.
Required package ‘dash-2.18.0’ is unavailable
Unable to activate package ‘lsp-pyright’.
Required package ‘lsp-mode-7.0’ is unavailable
Unable to activate package ‘lsp-mode’.
Required package ‘dash-2.18.0’ is unavailable
Unable to activate package ‘ht’.
Required package ‘dash-2.12.0’ is unavailable
Unable to activate package ‘flycheck’.
Required package ‘dash-2.12.1’ is unavailable
Unable to activate package ‘flycheck-pyflakes’.
Required package ‘flycheck-0.18’ is unavailable
Unable to activate package ‘flycheck’.
Required package ‘dash-2.12.1’ is unavailable
Unable to activate package ‘f’.
Required package ‘dash-2.2.0’ is unavailable

But I could get it back to work by just doing

M-x package-install RET dash RET

Try package-refresh-contents or change other mirrors, please.

Ah true, I also did a package-refresh-contents before installing dash! My mirror is standard "https://stable.melpa.org/packages/"

"stable melpa" is not recommended here.

I first had just "melpa" and faced the same problem.
