Errors fetching stage packages

snapcraft
1

Hi, I’ve not built a new version of my snap for a year. I am getting repeated errors when snapcraft is trying to download the two stage packages used in the snap:

Error Message: “Failed to fetch stage packages: Error downloading packages for part ‘photonotebook’: The package ‘liblcms2-2’ was not found…”

Has anyone any idea why this should happen? My snapcraft.yaml has not changed.

name: photonotebook

Hi @apdw,

I’m able to build this snap.

If you haven’t built this in a year, I wonder if the build environment is stale. If you’re using LXD, you can check with lxc info snapcraft-photonotebook. If it’s very old, I would run snapcraft clean --use-lxd and try again.

Do you happen to have Docker installed? That can cause issues with LXD containers not being able to access the internet.

Otherwise, please post the full logs, thanks!

Hi Mr Cal, Thanks for your reply. I tried what you suggested, but no change. No Docker installed! I’m running the build with the following script from the folder containing the snapcraft.yaml and the apps code and other apps dependencies:

snapcraft clean photonotebook
snapcraft clean gnome-3-38-extension
echo Snapping photonotebook
snapcraft --debug

Running the script gives the following terminal output:

I solution, or at least a workaround tried in desperation that seems to solve the problem!

instead of using:

snapcraft --debug

to snap my app, I tried

snapcraft --use-lxd --debug

to snap my app, and the problem went away, all stage packages found!

Cheers Alan
