Trying to upgrade an EX4300 getting an error Host Address Mismatch

Symptoms

Error while trying to upgrade,

NOTICE: uncommitted changes have been saved in /var/db/config/juniper.conf.pre-install

Pushing installation package to host...

Host address mismatch for x.x.x.x

Solution

Per RFC 1123, section 2.1:

 

However, a valid host name can never

          have the dotted-decimal form #.#.#.#, since at least the

          highest-level component label will be alphabetic.

 

A hostname can't use only number or an ip address, needs to add at least a letter, for example, this should work,

a1.1.1.1

1.2.3.4.in-addr.ss

033abc.cfd

abc123

123abc
