Panick on lauch

[TherryHilaire]

The app is able to launch without any problem, but when I try to to click on any button it crashes and the following error pops up:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Close', /build/nix-software-center-0.1.0-vendor.tar.gz/relm4/src/channel/component.rs:67:34
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Side note: I installed with nix-env.

Thanks for helping !

This is happening to me as well. Did you happen to fix it?

[TherryHilaire]

No

[Henry-Hiles]

I believe this works only on SnowflakeOS, perhaps that is the issue.

[vlinkz]

It should work on NixOS as well. The panic occurring inside the relm4 component for the file chooser seems to indicate that it might be a dependency issue, or possibly I need to update the relm4 version. Curious were you using GNOME or some other desktop environment?

I'm also getting this error on GNOME

Is that on SnowflakeOS or NixOS? Also if you run RUST_LOG=nix_software_center,nix_data=trace nix-software-center that can give a better insight than RUST_BACKTRACE

SnowflakeOS

Updated dependencies and made a few fixes that should address the initial crash @TherryHilaire and @camillemndn were facing. The issue @pinkcreeper100 has seems different, I tried to fix it with a few changes, but I was not able to reproduce it so not sure if that fixes it

[camillemndn]

Works like a charm! Thank you

[TherryHilaire]

I am not currently using nix so I cannot test if it does work. But it looks like it does for @camillemndn so it might for me.
