I got this following error when update or install software with pacman but It just runs the command as expected right after the error show up:

    ~  sudo pacman -Syy                                                                   ✔ 
[sudo] password for user:

I’m just curious about this error what does it mean and does It effects anything?

You are using a non supported third-party repo.
Judging from the name, it’s targeted towards Arch, you might be better off removing it from your config.

Could you show me how to remove it from my config?

[mithrial]

The config is in /etc/pacman.conf.

Use your favorite editor and remove the offending lines.

Yup there was some how a duplicated line:

[home_lamlng_Arch]
Server = https://download.opensuse.org/repositories/home:/lamlng/Arch/$arch

and after remove it the error is gone
