双指挥官30秒后开始，为什么？

Question

在之前安装Debian时，没有问题。双重指挥官立即启动。在另一台机器上的Linux上也是如此。

但是，由于我有一个新的Debian安装，doublecmd在大约30秒后就开始了。

有办法找出原因吗？

我试着重新安装这个应用程序，但是没有改变。

这看起来像是cups连接到本地主机的上下文，30秒后超时。

唯一重要部分的剪短：

剩下的看起来没问题。你有什么安排的杯子吗？您能否尝试在/home/vlastimil/.cups/client.conf中禁用它，可能是通过Browsing Off或BrowseLocalProtocols none？或者有可能用图形界面来设置.
