通过systemd服务/计时器将邮件与脱机映射同步；从gnome密钥环获取密码

Question

我正试图通过systemd服务使用offlineimap自动同步我的邮件。我正在使用这些文件，并将它们移到/etc/systemd/user文件夹中。

但是，我正在通过gnome密钥环存储我的密码，并通过secret-tool lookup user [user] domain gmail.com检索它。这在命令行中有效，但是服务返回以下内容：

user@computer:~/.dotfiles$ systemctl --user -l status offlineimap.service

我已经发现问题可能在于dbus通信，但我不知道如何解决它。有人能提供洞察力吗？

编辑：

我解决了与XOAUTH2相关的(无害的)警告，并按照这个论坛帖子的建议在存储库_帐户-远程部分添加了以下内容。

auth_mechanisms = LOGIN

然而，问题是无关的，但为了防止混淆，我已经相应地更新了上面的错误。

我可以想象的一个解决方案是使用系统环境变量或系统执行环境，并让您的offlineIMAP密码脚本回显环境变量，即密码。您还可以尝试使用客户端证书。
