[somekool]

I am trying to my first ubuntu package.

and push it to my own PPA

I am following this guide.

https://packaging.ubuntu.com/html/packaging-new-software.html

I have followed all the steps up to this point.

but bzr is crashing

here is the output
```

[somekool (somekool)]

awesome
thanks for the quick fix.

do you think I can except a package for Ubuntu 20.04 ?
I will for sure test it as soon as available

[somekool (somekool)]

since 20.04 is LTS, unless Breezy 3.1 is scheduled to be released soon, it seems this bug fixed should be backported to 3.0

my two cents

[somekool (somekool)]

I confirm, I checkout the 3.1 branch locally and I could proceed with the command without errors

[somekool (somekool)]

I am getting a different error now

You also need the trunk version of lp:brz-debian.

Status changed to 'Confirmed' because the bug affects multiple users.

This is fixed in breezy/breezy-debian, but Ubuntu still has an old version of those packages.

[Sam Varshavchik (mrsam)]

It would be useful if someone were to post the exact steps to work around this bug, so that someone who is trying to learn how to create packages and is following the published Ubuntu packaging guide documentation can, well, follow it.

As noted in bug 1897385, someone who's trying to learn how to create Ubuntu packages is not going to have any idea how to manually update to 3.1.0 where this is fixed, since it's not been published for 20.

[Zakhar (alainb06)]

Indeed mrsam!

My current workaround is to use 16.04 that I still have, and bazaar and how it is used in the Ubuntu documentation is still working there.

The limitation of doing so is that some libraries I need on my projects have since changed, and it does not "build" with 16.04. This is not an issue since I don't use locally built packages, but those from the launchpad.

With 16.04 you can still make the "source package" and post it to launchpad (dput last command) so it is unfortunately not a "blocker" for me. It might also work with 18.04 but I don't have it on my PCs, never really liked that version!

Crossing fingers that it would be solved for 22.04...

[Jelmer Vernooij (jelmer)]

Please file a bug against the packaging guide rather than breezy-debian.

This issue has been addressed upstream
in breezy-debian (which is not ubuntu-specific), where the dh-make wrapper
in breezy has been removed. This means than even if Ubuntu updates the
version of breezy-debian the guide will be incorrect.
