18.04: не удается установить texlive-full

Я недавно установил Ubuntu 18.04 на прошлой неделе, то есть я не обновлялся с 16.04, скорее отформатировал жесткий диск и установил 18.04.

Я пытаюсь установить texlive-full, но всякий раз, когда я использую:

sudo apt install texlive-full

, это то, что я получаю:
