Ethereum: How to update and older electrum version on ubuntu 17?
Updating and upgrading previous versions of Electrum on Ubuntu 17
As Ethereum’s popularity grows, so does the need for updates and upgrades to your cryptocurrency management tools. In this article, we will walk you through the process of upgrading and updating previous versions of Electrum on Ubuntu 17.
Why upgrade Electrum?
Before you dive into the upgrade process, it’s important to understand why you need to upgrade your version of Electrum. If you’re using an older version, you may be missing out on new features, bug fixes, and security patches that can improve your overall user experience and protect your cryptocurrency assets.
Installing Python 3 for Electrum
Before you begin the upgrade process, make sure you have Python 3 installed on your Ubuntu system. You can do this by running the following command:
sudo apt-get install python3
After installing Python 3, you will need to upgrade or downgrade it depending on your needs.
Upgrading Electrum
Now that we have covered the prerequisites, let’s update Electrum.
- Upgrade Python 3: We have already covered this step above. Make sure that Python 3 is up to date by running:
sudo apt-get update
- Upgrade or Downgrade Electrum: If you have an older version of Electrum installed (e.g. Electrum-3.0.4.tar.gz
), we will upgrade it to the latest version. Otherwise, we will install a new version.
To upgrade an existing Electrum installation:
sudo apt-get install python3-setuptools python3-pyqt5 python3-pip -o /usr/local/bin/python3
This command updates the Python 3 package index on your system and installs the latest available version of Electrum. If you want to downgrade, use:
sudo apt-get install python3-setuptools python3-pyqt5 python3-pip -o /usr/local/bin/python2
To install a new version of Electrum:
wget
tar xzf Electrum-3.0.7.tar.gz -C ~/electrum/
Here we have updated to the latest version (Electrum-3.0.7). This command extracts and installs Electrum from the provided archive.
Configuring Electrum for Ubuntu 17
After installing the new version of Electrum, you will need to configure it for use with your Bitcoin wallet. You can do this by creating a configuration file in the ~/electrum directory.
Create a new file called ~/.config/electrum/config.json(or create the directory if it doesn't exist):
{
"wallets": [
{
"name": "Bitcoin",
"url": "
}
]
}
Replace your-bitcoin-wallet-addrwith the actual address of your Bitcoin wallet.
Launching Electrum
Once you have configured the new version of Electrum, launch it by running:
~/electrum/electrum --config ~/.config/electrum/config.json
Done! Your Electrum installation should now be up to date and ready to use with your Bitcoin wallet.
Additional Tips
- Make sure to update all packages on your system before installing new ones.
- If you encounter problems during the upgrade process, try disabling apt-prefetch` by running:
sudo dpkg --set-selections <<< "apt-get install -f | grep -v '^apt-prefetch\|apt-get-\|pre\n' && sudo apt-get -o 'no-cache' upgrade"
This command disables package caching and allows you to update all packages again.
