If I than tried to follow the “first snap” example for python i.e. OfflineIMAP from this snapcraft.yaml at the staging part I get the following error:
Sorry, an error occurred in Snapcraft:
[Errno 17] File exists: 'libexpat.so.1.6.7' -> '/src/stage/lib/x86_64-linux-gnu/libexpat.so.1'
The thing that really leaves me quite confused is that, if I ask a friend who owns an Ubuntu Desktop laptop to reproduce the issue he can compile alright with no errors whatsoever.
I thought that the issue might be in the Dockerfile so I pulled this image and tried again, the exact error comes up at the staging step. I again asked my mate with Ubuntu to pull the same image and compile from the same yaml and again he succeeded with no issue.
At this point I am very puzzled. I thought that the whole point of using a container was that one can reproduce an environment independently on what OS is running the container from.
What am I doing wrong?
My Docker version is 19.03.8, build afacb8b
My Mac is running Catalina 10.15.5
I’ve just cloned the repo and run through a docker-based build. I did not hit the same problem, so something is amiss either with the images you tried or your command line, maybe.
Sure. After the initial apt install run I get to this part… sorry this is a lot of log

Staging test-offlineimap
Sorry, an error occurred in Snapcraft:
[Errno 17] File exists: 'libexpat.so.1.6.0' -> '/src/stage/lib/x86_64-linux-gnu/libexpat.so.1'
Can you run the following command from the directory you are building and paste the output, please? This is most odd with such a simple snap as offlineimap.
ls -l parts/offlineimap/install/lib/x86_64-linux-gnu/libexpat* stage/lib/x86_64-linux-gnu/libexpat*
Also could you share the full docker command you used, maybe you’re running it differently to me
Hmm, I wonder if this is something funky with the macOS-specific filesystem proxy that Docker are using? I’m going to try replicating on a macOS install rather than Ubuntu to see if that makes the difference.
Yes, I can replicate your issue using my container image in macOS. It looks to me like the symlink is being screwed-up somewhere by the osxfs in Docker for Mac.
