Está falhando porque archive.ubuntukylin.com está inacessível:

$ wget http://archive.ubuntukylin.com:10006/

Você pode evitar o erro se desativar o repositório em questão, pois ele não contém nada importante para executar o Ubuntu. Uma maneira de fazer isso seria:

grep -lZEe '^[^#]*archive\.ubuntukylin\.com' /etc/apt/sources.list{,.d/*.list} | xargs -r0 -- sudo sed -i -re '/^[^#]*archive\.ubuntukylin\.com/s/^/# /'
