version

i am learnig arduino yun on a ubuntu platfoform version 12.10 with arduino software version 1.5.6-r2, when i write example on usb arduino ttyACM0, I start application with sudo permission, I receive this message:

Lo sketch usa 1.116 byte (3%) dello spazio disponibile per i programmi. Il massimo è 32.256 byte.
Le variabili globali usano 11 byte (0%) di memoria dinamica, lasciando altri 2.037 byte liberi per le variabili locali. Il massimo è 2.048 byte.

the schetch i write is the example blink.
If I upload from wifi http://arduino.local it's ok.

Did you happen to follow your YUN's suggestion? Check that the proper board is selected, check your port settings, make sure drivers are properly installed.

Also, here is a post that may be connected: [SOLVED] Error after uploading to UNO (2 other MEGAs installed, too) - IDE 1.x - Arduino Forum
Sounds like a port issue to me...

I think also that you do not have the right board selected in the IDE, as the compiler output says you have only 2048 bytes of RAM available, while a Yun as should show 2560 bytes as available, not to mention that only 11 bytes of dynamic RAM being used doesn't look right, an empty sketch compiled (verified) shows on my system 151 bytes being used.
Likewise that you show 32.256 bytes as being available for code, a stock Yun shows me 28.672 bytes as available Flash ROM. Something isn't quite right here...
