Bug description

In version 3.13.1-1 of the Nextcloud client, virtual file support being enabled prevents the client from launching. When launching from the terminal, the /usr/bin/nextcloud binary crashes with Aborted (core dumped). The return code appears to be 134 from echo $?.

Downgrading to 3.13.0 with a cached package and changing no other packages or configuration allows the application to launch and function normally, with virtual file support being operational.

I have not tested in non-Arch distributions, but this version does operate as expected in a Windows VM. I have tested on two separate Arch installs, one AMD CPU- and GPU-based, the other Intel + Nvidia. Both crash.

Independently confirmed by @christian-heusel, who also provided the following crash backtrace (https://gitlab.archlinux.org/archlinux/packaging/packages/nextcloud-client/-/issues/6).

Steps to reproduce

Enable experimental options and have virtual file support enabled on a folder sync connection
Update nextcloud-client via pacman to 3.13.1-1
Client will crash with exit code 134
Downgrading the package without changing config files will allow it to operate again as expected

Expected behavior

Program should not exit quickly with an error code.

Related: #6819, but that is a minor version behind. This does not happen on Arch with 3.13.0 like in this issue, only 3.13.1.

christian-heusel · 2024-07-05T07:06:54Z

Against my initial assumptions this seems to be a downstream issue 😅

alerque · 2024-07-05T08:36:46Z

The Arch 3.13.1 package is built from the initial release of that version. The Nextcloud project silently dropped the release and retagged something like 3 days later with no explanation. (Don't do that @nextcloud, if something is wrong with your release or release process tag a new version and move on and save users and packagers a lot of headaches!)

kykorman · 2024-07-10T05:13:29Z

This has been resolved downstream.

cordlord · 2024-07-31T14:17:24Z

Just to chime in here for anyone else having this issue.

I just recently updated my distro and had this exact issue with this exact version.

I ran this to see what versions were available to me. Luckily, 3.11.0-1.1 was listed.

apt-cache show nextcloud-desktop | grep Version

I installed that version with the below command and my virtual files worked again! I also made sure to put it on hold so it doesn't automatically update on me and break again until they have it sorted.

sudo apt-get install nextcloud-desktop=FULLVERSIONTEXT
