When i generated a snap according to “IoT Graphics with Ubuntu Frame” document. I got a error when i used “snapcraft” command.

How do i solve the problem?

2

there seems to be an outage reported on status.snapcraft.io … try again a bit later …

3

This is an interesting error, are the yaml file permissions correct? And what version of Snapcraft are you using? If I try to reproduce the problem on 7.2.x using bad permissions, I get this:

$ snapcraft
Permission denied: 'snap/snapcraft.yaml'.
Full execution log: '/home/claudio/.local/state/snapcraft/log/snapcraft-20230215-095245.055746.log'
4

I tried it just. But it still not work correctly.

5

Hi, the snapcraft version is 7.2.9. it’s diffrent with my message.

6

Would you please share the file permissions for ‘snap/snapcraft.yaml’.

Is this the document you are following?

7

Would it be possible for you to share your yaml file, or a similar file that also causes the problem so we can reproduce it locally?

  • The first issue is thought to be a connectivity issue. Can you confirm that that part is now working?
  • What snapcraft backend are you using (Multipass / Lxd) and what version?
10

Thanks for your reponse.

1、how can i confirm the connect working? 2、I used Multipass and it’s 1.11.0

11

Where is your snapcraft.yaml located?

Multipass is a confined snap and may not have access to files outside your home directory. For example, if your snapcraft.yaml is in a mounted directory, you will get an error. I believe the error is about the source path not existing, not a snapcraft.yaml permission error. Still, I thought I would ask!

12

Ah interesting, this could explain what happened. But if this is the case, the error could be handled in a better way, ideally telling that the project could not be mounted in the build instance (or at least reporting a non-existing file instead of bad permissions).
