Setting up scx (1.6.3.326) ...
Failed to issue method call: Unit omid.service failed to load: No such file or directory. See system logs and 'systemctl status omid.service' for details.
dpkg: error processing package scx (--configure):
subprocess installed post-installation script returned error exit status 6
Errors were encountered while processing:
scx
E: Sub-process /usr/bin/dpkg returned an error code (1)
这很奇怪，因为我之前没有使用过docker pkg所以不确定为什么会出错。试图在docker网站上找到一些信息，但没有运气。
有人提出任何线索吗？
