apt-get error: update-initramfs: failed for /boot/initrd.img-2.6.31-20-generic-pae dpkg: subprocess installed post-installation script returned error exit status 1. E: Sub-process /usr/bin/dpkg returned an error code (2)

I got an error during Package installation in Ubuntu O.S..




The last line of that error i am mentioning bellow.



update-initramfs: failed for /boot/initrd.img-2.6.31-20-generic-pae dpkg: subprocess installed post-installation script returned error exit status 1.



i tried to run some command like



apt-get update

dpkg --configure -a

dpkg-reconfigure -a

apt-get --fix-broken install (apt-get -f install)



But this command was not worked.



Finally after some test I got the solution.



I checked the total error line which specifies the package which has been corrupted.



"""""""""""""""""""""""""""""""

Setting up initramfs-tools (0.92bubuntu53) ...

update-initramfs: deferring update (trigger activated)



Processing triggers for initramfs-tools ...

update-initramfs: Generating /boot/initrd.img-2.6.31-20-generic-pae



gzip: stdout: No space left on device

update-initramfs: failed for /boot/initrd.img-2.6.31-20-generic-pae

dpkg: subprocess installed post-installation script returned error exit status 1

E: Sub-process /usr/bin/dpkg returned an error code (2)



""""""""""""""""""""""""""""""""



Here the error code (2) is appeared for error code (1).

and the corrupted package for me is "initrd.img"



so then just I move that package to other location, (***don't delete it later it may require for you.)



"""""""""""""""""""""""""""""""""""

root@cloudtop:/boot# mv initrd.img-2.6.31-20-generic-pae /

""""""""""""""""""""""""""""""""""""

then I run



dpkg --configure -a

apt-get update



This has successfully configured it.



Now system is working fine and I can run apt-get without any error.



I don't know this is right procedure or not but its works for me.
