I am wondering where I can find update (refresh) logs for snap packages. Normally, apt updates can be found in /var/log/apt/ but where does snapd write its logfiles?

Thanks for your answer


snap changes will let you know what changed.


alan@gort:~$ snap changes
ID    Status  Spawn                 Ready                 Summary

  • Hi Popey, let me give you an example. I installed the magic device tool to flash my Ubuntu phone. The author will support a new device and I am waiting for the updated snap package. If MDT was installed as a .deb, Ubuntus update manager will pop up and inform me about the new version. Why doesn't it do that for snaps? How do I get the information about updated snap packages? – Laryllan Jun 1 '17 at 4:25
  • Snaps are designed to be auto updated in the background. Periodically snapd will check in with the store, and when the new mdt is released you'd get it. – popey Jun 1 '17 at 15:05
  • Sure, but how do I know I got it? Is there no way of knowing? – Laryllan Jun 3 '17 at 12:09

    You can "snap info <snapname>", but typically by the time you do that, you already got the update automatically. – popey Jun 7 '17 at 22:06
  • I cannot understand why snapd doesn't inform its users of updates. Not only doesn't it report when a snap updates - a changelog isn't available either. So a snap may update at will and completely change its contents without the user knowing. It's a bit scary, don't you think? – Laryllan Jun 9 '17 at 4:46
