Unable to update linux-image-2.6.24-21-generic

Linux-image-2.6.24-21-generic-general Linux technology-Linux programming and kernel information cannot be updated. See the following for details. The following error message prompted when updating the linux-image-2.6.24-21-generic some time ago:
E:/var/cache/apt/archives/linux-image-2.6.24-21-generic_2.6.24-21.42_i386.deb: unable to make a symbolic link backup for./boot/vmlinuz-2.6.24-21-generic before installing a new version
Because before updating the linux-image-2.6.24-19-generi, there are similar error message prompts, at that time is to deal with this, of course also in the Forum to get the method, not my original practice, but indeed have the effect:
Enter the following command on the terminal to successfully update the linux-image-2.6.24-19-generic
Sudo rm-fv/boot/initrd. img-2.6.24 *. bak
Sudo rm-fv/boot/vmlinuz-2.6.24-19-generic
Sudo rm-fv/boot/initrd. img-2.6.24-19-generic
Sudo rm-fv/boot/config-2.6.24-19-generic
Sudo rm-fv/boot // abi-2.6.24-19-generic
Sudo rm-fv/boot/System. map-2.6.24-19-generic
So you can refer to the above approach to update the linux-image-2.6.24-21-generic, that is, in the terminal input:
Sudo rm-fv/boot/initrd. img-2.6.24 *. bak
Sudo rm-fv/boot/vmlinuz-2.6.24-21-generic
Sudo rm-fv/boot/initrd. img-2.6.24-21-generic
Sudo rm-fv/boot/config-2.6.24-21-generic
Sudo rm-fv/boot // abi-2.6.24-21-generic
Sudo rm-fv/boot/System. map-2.6.24-21-generic
The update is successful immediately! It seems that this is a small BUG when the UB Chinese version is updated. We also hope that the UB masters can handle it as soon as possible.
