Why does apt-get want to remove gcc-4.8 and g++-4.8 when I try to upgrade?

Question

I am trying to upgrade gcc-4.8.1 and g++-4.8.1 to 4.8.2. I added the PPA containing g++-4.8.2, ran apt-get update and then when I try:

martin@martin-Studio-1537:~$ sudo apt-get upgrade
[sudo] password for martin: 
...
The following packages have been kept back:
  cpp-4.8 g++-4.8 gcc-4.8 gcc-4.8-base libasan0 libatomic1 libgcc-4.8-dev
  libgcc1 libgcc1-dbg libgfortran3 libgomp1 libitm1 libquadmath0
  libstdc++-4.8-dev libstdc++6 libstdc++6-4.8-dbg
0 upgraded, 0 newly installed, 0 to remove and 16 not upgraded.

the packages I need to upgrade are kept back. When I try:

martin@martin-Studio-1537:~$ sudo apt-get dist-upgrade
...
The following packages will be REMOVED:
  g++-4.8 gcc-4.8
The following packages will be upgraded:
  cpp-4.8 gcc-4.8-base libasan0 libatomic1 libgcc-4.8-dev libgcc1 libgcc1-dbg
  libgfortran3 libgomp1 libitm1 libquadmath0 libstdc++-4.8-dev libstdc++6
  libstdc++6-4.8-dbg
14 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
Need to get 14.9 MB of archives.
After this operation, 32.4 MB disk space will be freed.

the system wants to remove g++-4.8 gcc-4.8.

When I try to install gcc-4.8 from Synaptic It wants to remove g++-4.8 and when I tell that it is ok to remove it, I get this error:

How can I install gcc-4.8.2 and g++-4.8.2?

EDIT:

As souravc suggested, I did

martin@martin-Studio-1537:~$ dpkg -l | grep "^rc" | awk '{print $2}'

and this is the result:

autoconf

Solution 1

gcc 4.8.2 is currently under development and will only be released for trusty(14.04LTS).

The current latest version available for Ubuntu 13.10 saucy is 4.8.1 and it will not be updated to 4.8.2

Solution 2

You are getting this message as you have broken packages in your system. To be sure try this in your terminal,

dpkg -l | grep "^rc" | awk '{print $2}'

You should get a list showing above packages.

Run the following in a terminal to get rid of this,

sudo apt-get autoremove
sudo apt-get autoclean

To install gcc-4.8 and g++-4.8

sudo apt-get update
sudo apt-get install gcc-4.8 g++-4.8

@adityapatil It is not a duplicate. I read that question and did not solve my problem. If you see the solution in one of the answers, could you please post it as the answer to this question?

Have you tried all solutions? or at least those who are upvoted? Also read this.

[Martin Drozdik]

@adityapatil Those are not solutions to the problem I am solving.

try installing thrugh terminal using the options -fm.

[Martin Drozdik]

@adityapatil Thank you, but the result is the same. The system wants to remove g++-4.8 gcc-4.8 in exchange for upgrading the 14 packages.

Thank you, but I still get the same results. Moreover the list of packages I get (see my edit) is not the same as the ones I am trying to upgrade.

[sourav c.]

@MartinDrozdik there was a typo. sorry for that. did you run those autoremove and autoclean commands? are you still getting the notice when going to apt-get update?

[Martin Drozdik]

Yes, I typed the commands without the typo and it still doesn't work
