Notes on Ubuntu 14.04 LTS

Problem: apt-get update gives “Hash Sum mismatch”
create new list with http://repogen.simplylinux.ch/
edit /etc/apt/sources.list with the new list
sudo rm -rf /var/lib/apt/lists/partial/*
sudo rm -rf /var/lib/apt/lists/*
sudo rm /etc/apt/sources.list.save
sudo apt-get update

Persistent iptables:
sudo apt-get install iptables-persistent
to save the config: sudo invoke-rc.d iptables-persistent save

Enable hibernation:
https://help.ubuntu.com/14.04/ubuntu-help/power-hibernate.html

won’t shut down:
sudo nano /etc/default/grub
add “acpi=force” to the line “GRUB_CMDLINE_LINUX_DEFAULT=”
it might seem somthing like: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi=force”
