Hash sum mismatch during apt update, unwanted mirror is being used

I just installed Kali Linux VirtualBox 64 bit, and tried to perform 'sudo apt update'. And the error I received is:

E: Failed to fetch https://ftp.acc.umu.se/mirror/kali.o...64/Packages.gz Hash Sum mismatch
Hashes of expected file:

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

On my `/etc/apt/sources.list` the mirror I have is: http://http.kali.org/kali
So, why is the download even occuring from the mirror 'https://ftp.acc.umu.se/mirror/kali.org/kali'?
Is there any other place where I can replace this mirror with something that works?
Or is there some other solution to this problem?

And I have tried other solutions such as performing 'apt clean' or entering 'rm -rf /var/lib/apt/lists/*' and none of them work.
