error when installing brew

[umutkavakli]

Trying to install brew on ubuntu 20.04
using /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

I searched some discussions about this topic but I couldn't find any solution.

Also, when I check the ruby version with ruby -v
I got this version: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]

You'll have to install ruby 2.6 first.

Please don't use screenshots when sharing the output of commands in your terminal. They're often difficult to read and impossible to reuse (e.g. when looking up error messages). Instead, copy the text here and wrap them in three back-ticks (```) on the line before and on the line after to format them properly.

What @carlocab said, please post text as text, not screenshots.

That said, it looks like either your Homebrew cache directory (/home/ginger/.cache/Homebrew) is not writable, or you already have previous broken portable-ruby downloads that have incorrect permissions. Probably the fastest way to fix this: rm -fr /home/ginger/.cache/Homebrew, then run the installer again.
