我正在尝试通过 systemd 服务使用 Offlineimap 在 mutt 中自动同步我的邮件。我在用这些文件并将它们移动到该/etc/systemd/user文件夹中。
但是，我通过 gnome-keyring 存储密码并通过secret-tool lookup user [user] domain gmail.com.这可以从命令行运行，但该服务返回以下内容：
user@computer:~/.dotfiles$ systemctl --user -l status offlineimap.service

我已经发现问题可能出在 dbus 通信上，但我不知道如何解决它。任何人都可以提供见解吗？
编辑：
我按照建议在 [Repository YOUR_ACCOUNT-remote] 部分中添加了以下内容，解决了与 XOAUTH2 相关的（无害）警告这个论坛主题。
auth_mechanisms = LOGIN
然而，这个问题是无关的，但为了防止混淆，我相应地更新了上面的错误。
