Client installation

  1. Switch to root:

    su -

  2. Create a new source list file for the NextCloud Linux client:

    vim /etc/apt/sources.list.d/nextcloud-client.list

  3. Populate the file with:

    + deb http://ppa.launchpad.net/nextcloud-devs/client/ubuntu zesty main
+ deb-src http://ppa.launchpad.net/nextcloud-devs/client/ubuntu zesty main

    apt sources list example (nano)

    Choose the appropriate Ubuntu repo corresponding to the right Debian version:

    • zesty corresponds to Debian 9.x (Stretch)
    • bionic corrsponds to Debian 10.x (Buster)

  4. Install dirmngr to be able to access key servers (if not installed already):

    apt install dirmngr

  5. Do key related stuff (probably importing it from the cloud to the local key ring):

    apt-key adv --recv-key --keyserver keyserver.ubuntu.com AD3DD469

    gpg key output example

  6. Update the apt cache with the newly added repo data and install the nextcloud client:

    apt update && apt install nextcloud-client

  7. Once installed the nextcloud client can be started either from the application menu or from the terminal as a standard user:

    nextcloud
