Nextcloud Desktop Client AppImage

Today we released the first AppImage of the Nextcloud Desktop Client (2.3.2-beta). For more info see:

Feedback is appreciated!


Launches for me, but due to the lack of a Nextcloud server I could not test whether it syncs properly.

It works fine for me. Fedora 25, nextcloud 12.

I wonder what an AppImage is. I’m used to .deb and .rpm packages. A FlatPak would be sexy these days, but I’ve never heard of AppImages.


AppImage has, among others, these advantages:

  • Applications packaged as an AppImage can run on many distributions (including Ubuntu, Fedora, openSUSE, CentOS, elementaryOS, Linux Mint, and others)
  • One app = one file = super simple for users: just download one AppImage file, make it executable, and run
  • No unpacking or installation necessary
  • No root needed
  • No system libraries changed
  • Works out of the box, no installation of runtimes needed
  • Optional desktop integration with appimaged
  • Optional binary delta updates, e.g., for continuous builds (only download the binary diff) using AppImageUpdate
  • Can optionally GPG2-sign your AppImages (inside the file)
  • Works on Live ISOs
  • Can use the same AppImages when dual-booting multiple distributions

Debian 9 Stretch, Nextcloud 12. Works Ok if we do not use ssl…

How can I solve this issue?

As you left the URL, I went on it and you appear to have a self-signed certificate that could be a reason why it wasn’t accepted, and you might want to add your certificate using the third option.

In my case, I have the same issue than above:

but with a Let’s Encrypt certificate. Any ideas to solve this?

See here:

now with 2.5 it asks me everytime to log in agian when i start the app. Also it does not open in startup. Ubuntu 18.10

Fixed! I just purged my previous installation and and installed it again
sudo apt purge nextcloud-client
sudo apt install nextcloud-client

So there was just some hickup in the installation
