I just lost my Devises in Dolphin on the lower right hand side. So nothing shows when I plug in my external hard driver in the USB. I can't even do a backup of my files any more. This has never happened in the past. I really can use some help from developers please.....
Has anyone ran into this after this new update, or have found a solution to fix this? This really sucks!

Developers ....Please help!!

Same here. It was yesterday's 'solid' updates that caused the problem in dolphin.

Until the issue is solved there are two work-rounds:

1 - install the package:

thunar

devices are still shown

2 - rollback the three faulty packages:

libkf5solid5

libkf5solid5-data

qml-module-org-kde-solid

to versions 32 (the updated versions are numbered 33) and then lock these.

The Neon builds have imported this upstream change:

https://cgit.kde.org/solid.git/commit/? ... d1b0bb952b

but did not include the additional change:

https://cgit.kde.org/solid.git/commit/? ... ae140f980b

[UDisks] Only ignore non-user backing file if it is known
Only loop devices have this property, otherwise we end up ignoring regular disks as well.

BUG: 389358

Sorry I should have added that if you mount the drive in thunar it then shows in dolphin.

@gfielding,
You are a life saver! Thank you.
I see the drive now after I installed thunar, but can you tell me exactly how to roll back step by step?

The steps are:

1 - install the package:

synaptic

if not already installed.

2 - Open synaptic and enter:

solid

in the search box.

3 - Click on one of the packages to roll-back, then click on the top menu 'package', then 'Force Version' and select the previous version. Do the same with the other two versions and then apply.

4 - You can lock these three packages but Discover overides this, so you have to be careful when you do updates in Discover and just take the ticks out for the three packages just to update the other packages.

FYI, this issue is already fixed properly, so if you upgrade your system, it will fix the bug.

Thanks bshah

@gfielding, @bshah
It is fixed now as bshah mentioned.

Thank you guys , and developers, to jump on this so quick!

Hi,

I have a similar issue, when plugging in any USB driver nor Dolphin, nor the "Device Notifier" catches it even though dmesg reports the device has been recognized by the system.

Was this solved for the KDE Neon User Edition?

I have just tried a usb drive (user version of kde neon) and it was reconised fine. Perhaps try a different usb drive as a double check.

Didn't you read the tread? It's already fixed. Just refresh the Synaptic Package manager, or Discover, and do an update. The update will fix it.

Yes... Last dist-upgrade fixed the issue... Thanks...
