That hostname -i returns 127.0.1.1 is not a bug.

In contemporary Debian and Ubuntu, /etc/hosts should look like this:

    127.0.0.1 localhost
    127.0.1.1 foo

where "foo" is the Linux hostname and the content of /etc/hostname.
If the machine has a permanent IP address (123.45.67.89) and FQDN
(foo.bar.com) then it should look like this:

    127.0.0.1 localhost
    123.45.67.89 foo.bar.com foo

In the latter case "hostname -f" returns "foo.bar.com".

This is standard in Debian and Ubuntu and satisfies a number of desiderata:
* The hostname resolves to an address which resolves back the hostname or its FQDN variant
* "localhost" resolves to 127.0.0.1 which resolves back to "localhost"
* Each hostname resolves to a single IP address
* Each IP address resolves to a single canonical hostname
* The Linux hostname is resolvable

If software does not work with this configuration then that software is buggy.

It looks to me as if this report can be closed.
