If you have just installed Miro in Ubuntu, you may be wondering why trying to enable sharing results in an error message about the Avahi mDNSResponder Compatibility Library. There are two ways to do this. The first column you just click the button and click install, and the second one requires the execution of a command in the terminal, but may well be faster.
The Easy Way
All you need to do is install the Avahi mDNSResponder Compatibility Library, and then restart. No, most things in Ubuntu do not require a full restart, but this one usually does. Installation can be done in two clicks, one on the link below, and then clicking the install button in the Ubuntu Software Center.
