The ubuntu ppa still contains ETH classic. Is there a ppa for the hard-forked version of Ethereum?

Summary

  • The ethereum-dev ppa currently has geth v1.5.0-unstable
  • The ethereum ppa currently has geth 1.4.10-stable
  • Remove / purge your ethereum-dev ppa to use the non-dev v1.5.0-unstable version.



Details

From http://ethdocs.org/en/latest/ethereum-clients/cpp-ethereum/installing-binaries/linux-ubuntu-ppa.html:

Installing the “eth” command-line tool

WARNING: The ethereum-qt PPA will upgrade your system-wide Qt5 installation, from 5.2 on Trusty and 5.3 on Utopic, to 5.5.

For the latest stable version:

sudo add-apt-repository ppa:ethereum/ethereum-qt
sudo add-apt-repository ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install cpp-ethereum

If you want to use the cutting edge developer version:

sudo add-apt-repository ppa:ethereum/ethereum-qt
sudo add-apt-repository ppa:ethereum/ethereum
sudo add-apt-repository ppa:ethereum/ethereum-dev
sudo apt-get update
sudo apt-get install cpp-ethereum

If you have added the ethereum-dev ppa repository, you will currently have geth v1.5.0-unstable installed.

If you have only added the non-dev ethereum ppa repository, you will currently have geth 1.4.10 installed.

To remove ethereum-dev ppa:

user@Kumquat:~$ sudo apt-add-repository remove ethereum-dev

user@Kumquat:~$ sudo apt-get update
...
user@Kumquat:~$ sudo apt-get upgrade ethereum
...
user@Kumquat:~$ geth version

user@Kumquat:~$ geth help | grep dao
  --support-dao-fork   Updates the chain rules to support the DAO hard-fork
  --oppose-dao-fork    Updates the chain rules to oppose the DAO hard-fork



A safer way to remove your ppas would be to use the ppa-purge tool. From How can PPAs be removed?:

Use the --remove flag, similar to how the PPA was added:

sudo add-apt-repository --remove ppa:whatever/ppa

As a safer alternative, you can install ppa-purge:

sudo apt-get install ppa-purge

And then remove the PPA, downgrading gracefully packages it provided to packages provided by official repositories:

sudo ppa-purge ppa_name

Anyway, this won't uninstall packages that were on the PPA but not on tha official repositories. If you want to remove them, you should tell it to apt:

sudo apt-get purge package_name

You can also remove PPAs by deleting the .list files from /etc/apt/sources.list.d directory.

Last but not least, you can also disable or remove PPAs from the "Software Sources" section in Ubuntu Settings with a few clicks of your mouse (no terminal needed).
