Error installing on Ubuntu 20.04

I got his error:

`ubuntu@sol:~$ curl -fsSL https://raw.githubusercontent.com/m1guelpf/plz-cli/main/install.sh | sh -

Any suggestion?

Start by inspecting install.sh and the plz-linux-x86_64 release binary in the context of Ubuntu 20.04. Reproduce the installation and verify that the shell warning and GLIBC_2.32–2.34 errors are resolved, with plz running successfully afterward.
