For one user account when I go to "Reinstall Wordpress Core", I get error:

Hey there! Have the permissions or ownership on the files, or the wp-admin directory itself, been changed? If so, the system may not be able to read them.

A lot of files indeed were with 444 instead of 644.

Manually changed permissions to 644 and now it worked.

Thanks!
