Try...

sudo apt-get clean && sudo apt-get upgrade

It looks like the bash_4.2-2ubuntu2.1_i386.deb package on your system is corrupted.

Try...

sudo apt-get clean && sudo apt-get upgrade

It looks like the bash_4.2-2ubuntu2.1_i386.deb package on your system is corrupted.

I tried it, but it outputs the same error

That is odd as "apt-get clean" should have cleaned out the /archive ...what results then this code:

dpkg --contents /var/cache/apt/archives/bash_4.2-2ubuntu2.1_i386.deb



sometimes I wonder, and other times I just do not know

It appears that tar segfaulted. This is quite unusual. Try: sudo apt-get install --reinstall tar

[amrnegm]

when I run the command:

dpkg --contents /var/cache/apt/archives/bash_4.2-2ubuntu2.1_i386.deb
it outputs:

dpkg-deb: error: subprocess tar was killed by signal (Segmentation fault), core dumped

[Bashing-om]

amrnegm; Hey !

I have given some thought...what results:


ls -ld /var/cache/apt/archives/bash_4.2-2ubuntu2.1_i386.deb ##just to see what happens.
sudo rm -f /var/cache/apt/archives/bash_4.2-2ubuntu2.1_i386.deb ##remove it as it is corrupted.
sudo apt-get install --reinstall bash


no harm in try'n

thanks Bashing-om (http://ubuntuforums.org/member.php?u=1111508),

when I try your suggestion it outputs the following error:

dpkg-deb: error: subprocess tar was killed by signal (Segmentation fault), core dumped
dpkg: error processing /var/cache/apt/archives/bash_4.2-2ubuntu2.1_i386.deb (--unpack):

I think the problem is with tar itself, since it outputs the following error for just typing 'tar' in the shell:

Segmentation fault (core dumped)
I tried to install tar itself, but nothing changed.

Ok, let's see what the package manager has to say about "tar" :

dpkg -l tar will give a system status of that package.

Truly can not do much if "tar" is broke !
