Synaptic package manager is freezing when it attempts to download packages for installation.

I have tried to install using terminal, but I keep receiving a message saying: 'connection failed' 'unable to fetch some archives, maybe run apt-get update or try with --fix-missing?'

My internet connection is fine, what has gone wrong?

I'm only used to debian and apt, but I guess it must be the same.

When you try apt-get update it shows which server(s) it try to connect to. Are those servers reachable? Is apt set up to use a proxyserver which is not running?

These settings are under /etc/apt, for instance /etc/apt/sources.list or /etc/apt/apt.conf.d

Update: ign: means apt for some reason ignores the repository.

Try cd /var/lib/apt mv lists lists.old mkdir lists apt-get update

Try set | grep -i proxy grep -sir proxy /etc/apt

If it lists any proxy, is it responsive?

Update: So the the settings say there is supposed to run a HTTP_PROXY on port 4001

Either start it, if you know what it is, or remove the references to it. It could be set in your ~/.profile, /etc/profile or ~/.bashrc Or in your network settings.

For now, do a unset HTTP_PROXY and the other proxy-related keywords.

  • they aren't connecting. I just get Ign:1, Ign:2, Ign3: etc before each server ie: Ign:68 ppa.launchpad.net/elementary-os/stable/ubuntu xenial/main i386 Packages. I cant understand why I am getting no connection to the servers. Have had no problems installing packages either through synaptic or terminal until now.

  • I tried your first suggestion but no joy. $ set | grep -i proxy returned HTTP_PROXY='localhost:4001 ' and a whole list of stuff but when I tried $ grep -sir proxy /etc/apt still nothing. I have a proxy configuration in my network settings if that is of any use?
