I've looked into the assertion error and have figured out that src/shared/varlink.c is a file related to systemd. I then found that file is systemd's repository. A new version of systemd was released a week ago and I have done a full system upgrade a few days ago. This might be the issue.

Downgrading systemd to version 253 haven't helped

Thanks for reaching out! Tagging this as a feature request since we do not currently support Arch Linux for Outline Client.

We now have a CLI that should work on Arch Linux: https://github.com/Jigsaw-Code/outline-sdk/tree/main/x/examples/outline-cli

@cocoonkid also posted a workaround on this issue: https://github.com/Jigsaw-Code/outline-client/issues/1825

Seems to be broken on arch again. This error appears on both outline-cli and systemctl's outline_proxy_controller daemon. Is there a solution? Can i disable ipv6 manually and skip this step in outline?

[ERROR] 2024/03/18 21:45:59 failed to disable IPv6: failed to read IPv6 config: open /proc/sys/net/ipv6/conf/all/disable_ipv6: no such file or directory

UPD. My apologise, this error is caused BY manualy disabling ipv6. If someone get the same error, just remove ipv6.disable from grub kernel parameters.
