So I am on my college network which requires me to sign in to the browser before I start using the internet. I do so succesfully but on a clean install of Ubuntu, when I try to do
sudo apt update, I get the following output:
$ sudo apt update Get:1 http://in.archive.ubuntu.com/ubuntu xenial InRelease [2,847 B] Err:1 http://in.archive.ubuntu.com/ubuntu xenial InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?) Get:2 http://security.ubuntu.com/ubuntu xenial-security InRelease [2,854 B] Err:2 http://security.ubuntu.com/ubuntu xenial-security InRelease ...

E: Some index files failed to download. They have been ignored, or old ones used instead.
But when I do
wget http://in.archive.ubuntu.com/ubuntu/dists/xenial/InRelease, I get this output success:

Clearly I have internet access from my browser and on
wget but when I do
sudo apt (or
apt-get) update I get this error.
PS: This question is not similar to other threads as their solutions do not seem to work on mine
As I have found out, this problem is happening only to me, not others on the college network. Despite setting up the network according to instructions, this still happens. Any more help would be appreciated
EDIT: So as it turns out, 50% of us in the college are facing this issue, while 50% aren't despite having no issues with the hardware and sudo apt update before the last week. Thanks to @David Foerster for helping me throughout all this time.
As it stands, the issue has been raised to our college's networking department 🙂
