Is there any working way to currently build Wekan snap?
I have tried:

• Canonical’s build service
• docker
• lxc
• vagrant / VirtualBox Ubuntu 16.04 VM

And everything is broken.

[kubiko]

@xet7 I will have a look, in the mean time I'm testing manual local build if that works
I will let you know

[kubiko]

@xet7 it seems to be building fine locally, I'm just pushing devel build to store, and I will also build 1.23 from tag
You will need to release those, I will only push them to the store to be available there

[xet7]

@kubiko

How did you build them locally?

[kubiko]

@xet7 you can use any Ubuntu 16.04 machine(server or desktop), just install snapcraft. If you are running 18.04 or other releases, it's best to use lxc, I will prepare you short script for that case
Then:
$ snap install --classic snapcraft
and run within source tree
$ snapcraft
it will build snap package, no need to install any dependencies snapcraft will take care of everything
to clean, run
$ snapcraft clean

I have also now uploaded 1.23 release so once checked you can also release that one

When I tried to build in lxc, I did get these errors:

Do you have idea how to fix them?

It would also be nice if canonical's snap build server could be fixed.

@kubiko

I was able to build .snap package with clean install of Ubuntu 16.04.5, with snapcraft command. So now building manually works for me.

[xet7]

I needed to build snapcraft from source, to get Wekan snap package built.

[cjwatson]

I have a fix for the Launchpad snap build service awaiting deployment, so once https://bugs.launchpad.net/rutabaga/+bug/1781970 is marked "Fix Released" you should be able to retry that.

@cjwatson

I got this error in email:

Launchpad uploaded this snap package to the store, but the store failed to scan it:
DatabaseError: pgbouncer cannot connect to server
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
https://launchpad.net/~wekan-team/+snap/wekan-devel/+build/330020
Your team wekan-team is the requester of the build.

[cjwatson]

That was a transient problem in the store. Unfortunately the store upload retry logic is a bit buggy and broke with "A file with this exact same content has already been uploaded". I have some plans for fixing the buggy logic here, but in the meantime I suggest just requesting a fresh build.

[xet7]

Build service works now.

There is also new release of snapcraft with fix, although I have not tested it yet.
