I am really just linking some other great content here but there was something I had to figure out before I could follow the great guide by digital ocean.
I was getting these errors on the server after install when starting the install of dependencies:
W:Failed to fetch bzip2:/var/lib/apt/lists/partial/it.archive.ubuntu.com_ubuntu_dists_precise-updates_universe_binary-amd64_Packages Hash Sum mismatch
E:Some index files failed to download. They have been ignored, or old ones used instead.
The fix is actually pretty easy, just need to remove the content of the /var/lib/apt/lists directory:
sudo rm /var/lib/apt/lists/*
then the next command as there will be a directory which won’t remove as it is full of stuff, the last deletes the folder.
sudo rm -R /var/lib/apt/lists/partial/*
sudo rmdir /var/lib/apt/lists/partial
and then run:
sudo apt-get update && sudo apt-get upgrade
Sorted it for me and I’m sure it will for you. Now get back to digital oceans guide to cacti setup. Here’s the link again.
