Apt-get stuck at 0% [Working]

When I try to do anything with apt-get using a terminal, the apt-get gets stuck at 0% [Working].

Solution 1:

I came to this page via a high ranked Google search but these answers didn't help me. Instead I cleared out my local repository of retrieved package files with:

apt-get clean

Solution 2:

You can try to check the cache and to clean the cache directory.
In the order (each step is more deep, so stop as you find a solution):

• sudo apt-get clean (Update) on recent versions it will clear out the local repository of retrieved package files. It will be enough most of the time. It is (was) not so on earlier versions.

  It removes everything but the lock file from /var/cache/apt/archives/ and /var/cache/apt/archives/partial/.

• Look inside /var/lib/apt/lists/partial/ it should be empty.
  If not you can decide to empty it sudo rm /var/lib/apt/lists/partial/* eventually you may need sudo rm -f /var/lib/apt/lists/partial/*

• sudo apt-get check

  it updates the package cache and checks for broken dependencies.

• Shrink to a normal (not huge) number of repositories the list of /etc/apt/sources.list.
  If they are too many your system can hang in the attempt to build all the dependencies tree.
  You can create a minimal set of repositories from Ubuntu Sources List Generator site and after that you backup the /etc/apt/sources.list (with e.g. sudo cp -i /etc/apt/sources.list /etc/apt/sources.list.000) you can paste that instead of your present list.

• eventually you can check if you have a source lists file with https rather than http, but apt-transport-https is not installed (see the comment).
• try again sudo apt-get update and if it fails
• backup your /var/lib/apt/lists directory with sudo cp -r -p -i /var/lib/apt/lists ${HOME}/temp_apt_lists and after sudo rm -R /var/lib/apt/lists/*
• run sudo apt-get update again

It's possible you need to clean by hand some of the following directories (you can always backup them and only after delete the files inside) :

• /etc/apt/sources.list.d/
  File fragments for locations to fetch packages from. Configuration Item: Dir::Etc::SourceParts.
• etc/apt/preferences.d/
  File fragments for the version preferences. Configuration Item: Dir::Etc::PreferencesParts.
• /var/cache/apt/archives/partial/
  Storage area for package files in transit. Configuration Item: Dir::Cache::Archives (partial will be implicitly appended)
• /var/lib/apt/lists/partial/ Storage area for state information in transit. Configuration Item: Dir::State::Lists (partial will be implicitly appended)
• /var/lib/apt/lists/ Storage area for state information for each package resource specified in sources.list(5) Configuration Item: Dir::State::Lists.

PS> If you have succeed, remember to delete the backup copy that you don't need anymore, but not the sources.list.000 it can always be useful!

Update
There was an old bug because the package squid-deb-proxy-client does not clean up all its changes, solved so:

Removing the line:
Acquire::http::ProxyAutoDetect "/usr/share/squid-deb-proxy-client/apt-avahi-discover";

from:
/etc/apt/apt.conf.d/30autoproxy

Maybe can be useful this bug thread

More drastic remove the package if it is possible.
