Problems installing APM on Rpi

(Info) #1

Installation using sudo apt-get install apm-navio2 fails but also sudo apt-get update fails with a few erros on missing files.

Trying to compile from source encountered this problem:

pi@navio:~/ardupilot $ waf copter
Waf: Entering directory `/home/pi/ardupilot/build/navio2’

and this is the error running sudo apt-get update && sudo apt-get install apm-navio2

Dear Emlid Team,

I can confirm this, I have a similar issue. Somehow, the deb file seams not to be available on the emlid server.
Also if I try to do a wget http://files.emlid.com/debian/pool/main/a/apm-navio2/apm-navio2_3.4-rc1-20160609_armhf.deb, I get the message “file not found”.
I think this is an important issue as we are not able to install the software unless we compile it from scratch.
Thanks a lot!
