Recently I have been using ubuntu and as a CS student, i enjoy it quite a bit. unfortunately, as I am living in student halls and I have to use the given wifi and am not allowed to set up my own sub-network.(The halls have disconnected our ethernet ports)
After a week of using ubuntu perfectly fine. I keep getting NET:ERR_CERT_AUTHORITY_INVALID in chrome. Also, I have tried firefox but again I am getting "this connection is not secure". I understand that I have to log into an account to access wifi/internet access but any browser in Linux won't let me. Previously I was not asked to log in but my internet worked perfectly fine.
What I have already done so far to try and resolve this issue.
- Set the correct date and time for my location.
- Deleted all browsing history twice. (This got the internet to work and 10 seconds later it came up with the same error.)
- This How do I deal with NET:ERR_CERT_AUTHORITY_INVALID in Chrome?
- And this http://www.toppctech.com/fix-net-err-cert-authority-invalid-error/ (Fix 1 does not exist in my version of chrome)
I am using chrome v54.02840.90(64-bit) on Ubuntu 16.04LTS
