Cannot update Ubuntu

[Gil Levy]

Not sure if it's Unbound related, but this problem appeared after
installing unbound on Ubuntu 20.04 on an Oracle cloud instance.

If I issue #: sudo apt update
I get:
Err:1 http://ap-sydney-1-ad-1.clouds.archive.ubuntu.com/ubuntu focal
InRelease
  Could not connect to 127.0.0.1:8080 (127.0.0.1). - connect (111:
Connection re
fused)


This is my proxy.conf file:
  GNU nano 4.8 proxy.conf
Acquire {
  HTTP::proxy "http://127.0.0.1:8080";
  HTTPS::proxy "http://127.0.0.1:8080";
}

If I set it to 5335 (the port for unbound) then I get:
0% [Waiting for headers] [Waiting for headers] <-- this is stuck.

Did anyone else encounter this?

Thanks.
