Function Fix-PSRepository {
    <# 
    Fixes the issue with PSGallery:
    Find-Module <module_name>  -> does not find anything
    Get-PSRepository -> returns "Unable to find module repositories"
    
    Register-PSRepository -Default -Verbose -> should fix it but behind the proxy, following should be run first

    #>
    [system.net.webrequest]::defaultwebproxy = new-object system.net.webproxy('http://proxy_address:proxy_port')
    [system.net.webrequest]::defaultwebproxy.credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
    [system.net.webrequest]::defaultwebproxy.BypassProxyOnLocal = $true

    # now this should work and register the PSGallery as default
    Register-PSRepository -Default -Verbose

    # And this should return PSGallery with its installation policy and source location
    Get-PSRepository
