That worked @danielvartan, thanks!

@rcgrosado, Positron do not rely anymore on the Copilot Language Server binary. I had to logout and login with my GitHub account to make it work again.

The latest version is giving me errors, even after downloading the latest Copilot Language Server. This one I hadn't had before:

The Copilot Language Server bundled with Positron is failing again.

I had to update it to the latest version in Positron 2025.12.0.167-1 to get Copilot working again.

If you are having this issue, try the steps in this comment: https://github.com/posit-dev/positron/issues/476#issuecomment-3239580585

I experienced problems with the copilot-language-server extension file when installing 2025.10.1.4-1, which is based on Positron-2025.10.1-4-x64.deb.

Initially, I could not authenticate myself with GitHub Copilot using the Positron Assistant. I raised an question on the Positron discussion forum here: https://github.com/posit-dev/positron/discussions/10027. That discussion led me to look at the copilot-language-server extension file, which was getting corrupted during the installation, though I am not sure why or how or whether I was doing something wrong.

In any case, I made a new PKGBUILD, which is available here for anyone interested: https://github.com/mark-andrews/positron-ide-archlinux-installer.

This seems to working for me now. It installed Positron without issues and I can use GitHub Copilot now and nothing else seems to be malfunctioning.

For those of you wondering about the lack of update, since 2025.09.0-139 is still bugged I have been waiting for the next release version to come out.

@produnis - This has always been the same release-based dev (and deb) binary pacakge! The dailies came later, which I do not plan on packaging.

so, is this still die "dev" version or a "stable" one?

In case it is of value of others, here's a patch that I used to bring this package up to date with the 2025.09.0-139 debs from Posit. Save the code below to a file named e.g. update.patch, clone https://aur.archlinux.org/positron-ide-devel-bin.git, do git apply update.patch, then makepkg -s and then sudo pacman -U the zst file. It works fine for me.

Regarding the GitHub Copilot issue: it originates from the version of the Copilot Language Server bundled with Positron. See this issue for a fix.
