Support Installation and Configuration

Hi guys, I’ve just installed Parrot 4.9 with the OVA official image in VirtualBox with a Windows 10 host. Once booted I try to do an apt update but I can’t because of this error:

E: Some index files failed to download. They have been ignored, or old ones used instead. ```

I think I've already tried literally everything. Starting from an easy `sudo rm -rf /var/lib/apt/lists/*` and `apt clean` but same problem. I've tried changing the mirror list but also with that same error. 
`sudo apt -o Acquire::https::No-Cache=True -o Acquire::http::No-Cache=True update` don't work also. I've also tried to change connection with a one without a proxy, cleaned the lists directory but also with this attempt i was not lucky.

I think that also the "green turtle" icon on VirtualBox is not helping but i followed with attention this thread https://forums.virtualbox.org/viewtopic.php?f=6&t=90853&sid=dd153bd7f58ac95966ee195414bdf7a5&start=270#p476261 but yes, i deactivated all the linux subsystem e stuff on windows, turned off the hypervisorlaunchtype  but nothing.. the turtle still be there and I still have this frustrating problem of the mismatch of the hash.

Does someone have any clues?

[SOLVED]

Reinstalling Windows from scratch solved the problem.

Disabling hyper-v and then restart the host windows

Start cmd as admin
Type
bcdedit /set hypervisorlaunchtpye off
Press Enter
Restart

Didn’t worked, the only solution that worked was to reinstall windows form scratch…
