@abu-matterize can you try the suggestions mentioned in the error logs?

[abu-matterize]

yes. worked, planning a per-flight check implementation for install.sh?

[shubhamdp]

@abu-matterize What do you mean by per-flight check implementation for install.sh?

[abu-matterize]

like the version checks of deps?

[shubhamdp]

I do not understand what you are trying to say, could you elaborate a little?

[cyberxnomad]

I'm encountering the same problem.
The error message suggests that Python versions above 3.12 are not supported.
My OS is Debian 13, and it ships with Python 3.13 by default.
It looks like this might require bumping the pyo3 version.

I've also tried setting PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1, but that didn't work either—it just caused other problems during installation.

[cyberxnomad]

Hi, @abu-matterize .

May I ask how you resolved this issue? Did you downgrade Python to version 3.12 or use another approach?

[abu-matterize]

yes, i downgraded python to fix it.

[shubhamdp]

@abu-matterize @cyberxnomad can you try the below fix with Python3.13 and share your feedback?

cd esp-matter

curl https://github.com/shubhamdp/connectedhomeip/commit/a1ee591102ef5f95c886fcc9834af6b1111968dc.patch | git -C connectedhomeip/connectedhomeip am

rm -rf connectedhomeip/connectedhomeip/.environment

./install.sh

[shubhamdp]

I tried this on the clean setup inside docker and ran into similar issue, raised the fix here: project-chip/connectedhomeip#43575, will backport to v1.5 once merged and update the submodule

[cyberxnomad]

Hi, @shubhamdp.

I've given it a try, and it seems a new issue has come up:

Hello, @shubhamdp .

May I kindly ask whether the connectedhomeip/connectedhomeip submodule for release/v1.5 has already been frozen? I see that its last update was five months ago.
