Nexctloud Client won't update on KDE Neon 20.04

Nextcloud won’t update on KDE Neon to 3.1.0 because of qtbase-abi-5-12-8, which doesn’t exist.

Any idea how to fix this?


After some exploring, qtbase-abi-5-12-8 is normally supplied by libqt5core5a but this is already installed in Neon by default. Neon’s current version as of this post is 5.15.2+dfsg-0xneon+20.04+focal+build23 which suggests that the Nextcloud package is not finding qtbase-abi when it is using a newer version than qtbase-abi-5-12-8.

I’m guessing that the qtbase-abi version is in someway hardcoded?

While it isn’t the latest version, current versions can be installed in Neon with:

pkcon install dolphin-nextcloud

Unfortunately, dolphin-nextcloud depends on nextcloud-desktop so that’s a no-go.

You can try to install the AppImage from Install – Nextcloud . It worked for me

As another option, Flathub has version 3.0.2 as of this writing.

But we loose file manager integration with the AppImage / Flatpack / Snap, right? Is there a way around it?

Right now, I just have mine on hold. Hopefully this gets resolved.
