I consistently (several weeks already) get the error:

```
Unable to connect to mozart.ee.ic.ac.uk:http:
Failed to fetch [package name] 

```

I am Using Linux Mint 19.3

Every time I do a `apt-install` (anything) or apt update (with and without `sudo`) it starts running, downloading several items until it gets to the `mozart` site, where it hangs for a while and then gives up.

Is there a solution to this?
