升级遇到错误

信息如下：
(Reading database ... dpkg: error processing /var/cache/apt/archives/hdparm_5.8-1_i386.deb (--unpack):
unable to open files list file for package `gnome-swallow-applet': Unknown error 990
Errors were encountered while processing:
/var/cache/apt/archives/hdparm_5.8-1_i386.deb
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)


现在已经完全不能更新系统了。请问如何解决?

rm /var/cache/apt/archives/hdparm_5.8-1_i386.deb
dpkg -P --force-all gnome-swallow-applet

然后再试试能不能更新系统。
