How to contribute and how to create snap are not well documented.
I installed all dependencies from this instaruction https://github.com/canonical/ubuntu-desktop-provision/blob/main/docs/CONTRIBUTING.md#required-dependencies
my branch was ubunt/24.04
melos boostrap worked
after that
git checkout smap/ubuntu-desktop-bootstrap
snapcraft
it builds a snap file.
if I install this snap and execute ubuntu-desktop-bootstrap --try-or-install
I get white windows and this error
`# ubuntu-desktop-bootstrap --try-or-install
Failed to start udisks2-inhibit.service: Unit udisks2-inhibit.service not found.

Can someone help how to build a working snap from source code? if I install it from snap store it works. I need to modify source code
Thanks in advance

We'll need to know some more details of the system you are attempting to run the installer snap on to be able to help. The error you are seeing around glibc not being found sounds like you may be running on an old version of ubuntu that is incompatible with the installer? (The same applies for the warning about no GL implementation being available).

Thank you for your answer.
These are ubuntu and glibc versions.

I also tried older version of ubuntu

If I install it from snapsore it works.
But if i build it as i above described. It says glibc not found.
I use flutter 3.19.2-stable

I suspect you're trying to build the snap from snap/ubuntu-desktop-bootstrap/24.04 using snapcraft 8.x, which causes the library path issues you describe. See #842 for more details. You should be able to resolve this by building the snap using snapcraft from 7.x/stable (it's pinned to that version on launchpad as well).

It worked thank you very much
