signal-desktop does not appear to be in their aarch64 repo anymore… are there any news on integrating it to the ARM repo? (there’s now a version for Mobian so it’s confirmed to work on ARM)
It would be even nicer now than before since recent desktop versions (5.26 beta+) have collapsible contact bar, which means that they could be used properly on the PinePhone
Signal is not easy to build for aarch64, as it requires a lot of dependencies not in the Arch Linux ARM repositories and it has even had compile issues on aarch64 in the past.
EDIT: for now the 5.25 version does not work since it requires GLIBCXX_3.4.29 which does not seem to be included in the libstdc++ of the ARM repo yet but some older versions should work.
