installation error on MACOS (Big Sur 11.7.1)

[silvia1234567890]

Hello,

I am trying to install Homebrew on my pc and I get the same error every time.

"
Error: Checksum mismatch.
Expected: 61029cec31c68a1fae1fa90fa876adf43d0becff777da793f9b5c5577f00567a
Actual:
Archive: /Users/Ana/Library/Caches/Homebrew/portable-ruby-2.6.10_1.el_capitan.bottle.tar.gz
To retry an incomplete download, remove the file above.
Error: Failed to install Homebrew Portable Ruby (and your system version is too old)!
Failed during: /usr/local/bin/brew update --force --quiet
"

Also, I tried to install the Homebrew-4.1.2.pkg and at the end of the installation I got an error message.
Could you help me please?

Thank you in advance,
Best regards,
Silvia

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.

Looks like the perl that comes with your system is broken for some reason. What's the output of

/usr/bin/shasum -a 256 /Users/Ana/Library/Caches/Homebrew/portable-ruby-2.6.10_1.1_capitan.bottle.tar.gz

?

Can keep talking here but closing as not a Homebrew issue.
