<div dir="ltr">Hi <div><br></div><div>I remember I successfully compiled the Ubuntu-clock example long time ago. Today, I tried to build it again using the latest snapcraft to build. However, I got an error like the following? What could be the problem for it? I am building it on 16.04, and my snapcraft versin is 2.12. I also got the same problem when build the sample app webcam-webui, and I reported at <a
