Upon installing connman, I get this error:
      Code:

Post subject: RE: Can
According to your previous post, it appears that connman was just installed on your system because of relatively far fetching recommends, rather than you intentionally installing it in order to manage your networking setup instead of ifupdown | systemd-networkd | network-manager. If this is the case, I'd suggest to simply remove (purge) connmann again, instead of actually debugging the underlying issues (having multiple networking dæmons installed, each trying to exclusively take over all aspects of your networking is a recipe for havoc).

If you have a particular reason to use connman instead of your existing networking setup, we can revisit this issue. While connman has some interesting traits, we don't use it in any aptosid flavour, nor really actively support it, which doesn't imply that it shouldn't work, just that it might need special configuration and/ or a clean slate.


aptosid has exclusively favoured ifupdown for networking needs so far, upcoming versions will likely use systemd-networkd by default (at least for the simple ethernet && dhcp case).

Yes, connman was brought in automatically by an 'apt install lxqt' command. And I purged it after failing to get it to connect to my wifi network. All I could do with it is turn the "power" on the interface on and off, which seemed the equivalent of doing an 'rfkill unblock' on the device. I found that installing connman not only removed the resolvconf package, but also left my wireless soft-blocked. I was just trying connman to see if it provided an easier way to reconnect to wifi vs. using the command line. But my connection is enabled automatically at boot and is usually pretty stable these days.

I don't have suggested or recommended packages installed automatically.
      Code:
cat /etc/apt/apt.conf.d/80aptosid
// apt defaults for aptosid
// apt 0.7 introduces automatic behaviour unsuitable for sid, revert this

// auto-remove breaks on meta packages
APT::Get::AutomaticRemove "0";
APT::Get::HideAutoRemove "1";

// Recommends are as of now still abused in many packages
// APT::Install-Recommends "0";
APT::Install-Suggests "0";
Debug::pkgAutoRemove "0";

// PDiffs reduce the required download for apt-get update, but increase the
// CPU requirements and quite often fail.
// Acquire::PDiffs "0";

apt-cache rdepends connman

Oops, it appears I do actually have Install-Recommends turned on, I forgot about that. The line in 80aptosid that turns it off is commented out. Good to know.
