o software parou de funcionar no Ubuntu 14.04 [duplicado]

Question

Anteriormente, não tive nenhum problema com o Centro de Software. De repente, quando abro o Centro de Software, uma mensagem de erro é exibida:

E:Unable to parse package file /var/lib/apt/lists/in.archive.ubuntu.com_ubuntu_dists_trusty-updates_main_i18n_Translation-en (1), E:The package lists or status file could not be parsed or opened.

e quando eu abri-lo através do terminal, ele mostra a mensagem de erro como
