I was trying to run apt-get update for some reason (I can't remember why now) and it threw all these errors:
Code:
Get:1 http://http.kali.org/kali sana InRelease [399 B]                         
Get:2 http://security.kali.org/kali-security sana/updates InRelease [399 B]
Err:1 http://http.kali.org/kali sana InRelease
  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
Err:2 http://security.kali.org/kali-security sana/updates InRelease
  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
Fetched 399 B in 29s (13 B/s)    
Reading package lists... Done
W: Failed to fetch http://http.kali.org/kali/dists/sana/InRelease  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
W: Failed to fetch http://security.kali.org/kali-security/dists/sana/updates/InRelease  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: Some index files failed to download. They have been ignored, or old ones used instead.
Any idea what the problem is? Any help would be greatly appreciated, thanks!
