HACS Problems

Hello,
I wanted to install new repository in HACS, but failed to. When I chose one, window with Author/Stars etc. shows up but stuck in endless loop and never loads. I tried updating HACS, got 1.23.0 and saw version 1.32.1 is available. Unfortunately i get such error when I try updating:
"No RepositoryFile.MAINIFEST_JSON file found ‘custom_components/hacs/RepositoryFile MAINIEST_JSON’
Any ideas what might be wrong in here? I tried: “wget -O - https://get.hacs.xyz | bash -” as mentioned on other topic, but it’s not working for me:
image

it’s O (the letter) not 0 (zero)

You write the parameter as -O in the text, but your screen dump has the parameter as -0 (zero).

Retyped that, got such information:
image
HACS still not updated

Your command is still wrong.
There is no output for the -O parameter.
Check it again.

Thank you, it has worked now.
