Cannot remove codeblocks using apt-get - Ubuntu 14.04 [duplicate]

Question

Whenever I try to run sudo apt-get remove codeblocks I am met with this message: The following packages have unmet dependencies:

codeblocks-contrib : Depends: libgamin0 but it is not going to be installed
                      Depends: libwxsmithlib0 (= 13.12-1) but 13.12-3 is to be installed
                      Depends: codeblocks (= 13.12-1) but it is not going to be installed
                      Recommends: cppcheck but it is not going to be installed
                      Recommends: cscope but it is not going to be installed
                      Recommends: cccc but it is not going to be installed
 codeblocks-dbg : Depends: codeblocks (= 13.12-3) but it is not going to be installed
                  Depends: codeblocks-contrib (= 13.12-3) but 13.12-1 is to be installed
 libwxsmithlib0 : Depends: libcodeblocks0 (= 13.12-3) but 13.12-1 is to be installed
                  Recommends: codeblocks-contrib (= 13.12-3) but 13.12-1 is to be installed
 libwxsmithlib0-dev : Depends: libwxsmithlib-dev (= 13.12-3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I then try to use sudo apt-get -f install, there's a prompt to install some software then I'm met with this message and error:

Unpacking codeblocks-dev (13.12-3) over (13.12-1) ...
dpkg: error processing archive /var/cache/apt/archives/codeblocks-dev_13.12-3_amd64.deb (--unpack):
 trying to overwrite '/usr/include/codeblocks/externaldepsdlg.h', which is also in package codeblocks-headers 13.12-1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/codeblocks-dev_13.12-3_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Any suggestions? I've tried sudo apt-get remove codeblocks, but i'm met with nearly the same unmet dependencies error as before.

The reason I am trying to remove codeblocks is that I am trying to install gnome-themes-standard, but I was met with a similar unmet dependencies error (same packages listed). I'm guessing that something with the apt-get may be corrupted: I recently dual-booted windows 10 and moved a few OS partitions around.

Solutions I have tried:

1. sudo dpkg --configure -a
2. Removing codeblocks-contrib and libwxsmithlib0
3. sudo apt-get autoclean
4. sudo apt-get clean

If anyone knows how to fix this, please help.

If anyone is curious, I did get these errors when I used sudo apt-get update while writing this

Reading package lists... Done
W: GPG error: http://download.opensuse.org  Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A7D1D38BEB6D886
W: GPG error: http://ppa.launchpad.net precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B70731143DD9F856

EDIT

So I was able to actually solve the GPG error with http:\\ppa.launchpad.net through this which is summarized here:

1. I copied the current pubkey that is output (B70731143DD9F856)
2. Searched the key in keyserver.ubuntu.com as a hexidecimal (bascially formatted with a 0x => 0xB70731143DD9F856)
3. Pressed the pubkey link Copied the entire textblock (includign the ---begin--- and ---end--- lines)
4. Pasted it into a text editor, saved it as key1 Ran sudo apt-key add key1 in key1's directory then received an OK

and when I reran sudo apt-get install, the error on ppa launchpad was gone, but the other GPG error persisted. Trying this method with the opensuse error does not work as a search in the Ubuntu keyserver turns up nothing

Answer 1

While revisiting this error today, I came upon the solution proposed in this forum post. It turns out that the issue is caused by the cross dependency between several of the codeblocks packages, so the entire install needs to be repaired using this command:

sudo apt-get purge codeblocks-contrib-dbg codeblocks-libwxcontrib0 codeblocks-dbg \
codeblocks-dev codeblocks codeblocks-headers libcodeblocks0  codeblocks-contrib \
codeblocks-contrib-common codeblocks-wxcontrib-headers codeblocks-wxcontrib-dev \
codeblocks-common libwxsmithlib0 libwxsmithlib0 libwxsmithlib0-dev

copied in as one line in the terminal. After processing, I could once again successfully install software.

you should run this command:

sudo apt-get purge *codeblocks*
