Hey @ux370 — sorry for the slow response, took a couple days off!

Fixed in v9.1.3:

pipx upgrade trcc-linux

If anything else comes up, just reply with a trcc report and I'll take a look!

Hey @ux370 — you're on v9.0.9, we're now at v9.2.1 which has a lot of fixes since then. Can you upgrade first and try again?

Since you installed via pip on Ubuntu 24.04, grab the native DEB instead — it's much more reliable on Ubuntu:

wget https://github.com/Lexonight1/thermalright-trcc-linux/releases/latest/download/trcc-linux_9.2.1_amd64.deb
sudo dpkg -i trcc-linux_9.2.1_amd64.deb

Then run trcc report and let us know if the download error persists.

Hey @ux370 — just checking in! We're at v9.2.4 now. Grab the latest DEB from the releases page and install with:

sudo dpkg -i trcc-linux_*.deb

Let us know if the download error still shows up!
