v1.3.2 and latest commit from master branch

Issue/Bug Description:

Both the last stable release and last commit no longer build on Arch Linux, this has been reported to me today and have confirmed the issue

Rust is at v1.74.1

Steps to reproduce (if you know):

Install Arch Linux sudo pacman -Syyu base-devel git git clone https://aur.archlinux.org/popsicle.git cd popsicle makepkg -s

popsicle-git on AUR still have old build instructions at the moment, realized now when checking, I have updated it locally for now

Expected behavior:

pkgbuilds build fine

Other Notes:

Similar problem for Nix: https://github.com/NixOS/nixpkgs/issues/269914

[mmstick]

I'll check it out. Probably just needs a dependency update

[tormeh]

Indeed, a similar problem seems to have been fixed for Zenith with a dep update: https://github.com/bvaisvil/zenith/pull/135

Still doesn't build:

Confirm is not resolved yet

[mmstick]

Depends on https://github.com/mdaffin/loopdev/issues/62 being resolved

[mmstick]

Try building from the branch at https://github.com/pop-os/popsicle/pull/210

[yochananmarqos]

Yes, it builds now.

[FabioLolix]
