The oficial documentation can be found here.

E: Package 'cassandra' has no installation candidate when installing Cassandra – Debian

I was trying to uninstall and reinstall Cassandra on my Ubuntu system however in an attempt to cleanup I deleted file names with cassandra in it, and accidentally deleted requisite file including the /etc/apt/sources.list.d/cassandra.sources.list file. And now when I try to install Cassandra using the command sudo apt-get install cassandra, it gives the error E: Package 'cassandra' has no installation candidate. How can I fix this?

I ran sudo apt-get update and the cassandra.sources.list file seems to have come back, with content deb [arch=amd64] https://downloads.apache.org/cassandra/debian 311x main but it still gives same error on trying to install cassandra

    I was able to follow the documentation to install cassandra, the only thing that I adjusted was the curl -L flag but apart from that this can solve your problem.

    $ echo "deb http://www.apache.org/dist/cassandra/debian 40x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
deb http://www.apache.org/dist/cassandra/debian 40x main

# Make sure the `cassandra.sources.list` file has only this single line.

$ sudo cat /etc/apt/sources.list.d/cassandra.sources.list
deb http://www.apache.org/dist/cassandra/debian 40x main

$ curl -L https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -

OK

$ sudo apt-get update
$ sudo apt-get install cassandra

    This error indicates that APT was not able to find a source for the package:

    E: Package 'cassandra' has no installation candidate

    The cause for the error is that you added the wrong repository in your sources:

    deb [arch=amd64] https://downloads.apache.org/cassandra/debian 311x main

    If you have a look at the Cassandra installation document I wrote on the Apache website, the correct repository is www.apache.org/dist/cassandra/debian.

    If you want to install Cassandra 3.11, You need to delete your source and update it with:

    $ sudo rm /etc/apt/sources.list.d/cassandra.sources.list
$ echo "deb http://www.apache.org/dist/cassandra/debian 311x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list

    You’ll need to follow the document above to add the repo keys and update the package index on your server. Then to install C* 3.11.11 (for example), run:

    $ sudo apt-get install cassandra=3.11.11-1

    You’ll need to adapt the command above to the specific version you want to install. Otherwise, APT will attempt to install the latest version. Cheers!
