Following installation of KDE apps 19.04, I found that gdrive no longer functions within Dolphin. If I click my gmail account name on the left hand panel, Dolphin returns the message: "Unable to create io-slave. klauncher said: Error loading '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/gdrive.so'".

I have checked that gdrive.so is installed within the above directory. In addition, kio, kio-gdrive, kio-extras and kio-extras-data are all installed, along with kaccounts-integration, kaccounts-providers, and libkaccounts1.

User forums have some advice on this problem, mostly along the lines of "remove gdrive and your gmail account from Online Accounts in Settings, reboot, then reinstall". I have tried this, but with no success - I still get the above error message.

Is this a known problem following KDE apps 19.04, or is this just a coincidence? Certainly gdrive was working well before 19.04 came along. Any help or advice you can give will be gratefully received. Thank you.

Probably just a coincidence, I just tried here, works fine. Mind you, I only just set it up for the first time, maybe erasing all your google.com instances in the setup and recreating it might help.

Same problem as friend suffolkman.

Everything worked fine before the last update.

Same problem here.
I can also confirm that deleting & reinstating your Google account in "Online Accounts" doesn't work.

I can confirm that setting this up for the first time on KDE Neon (with applications 19.04) gives the "Unable to create io-slave. klauncher said: Error loading '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/gdrive.so'" error in Dolphin.

Here's a possible workaround. I have been using Insync instead of grive for several years now with no issues. I am assuming gdrive does the same thing as grive.

You may have to pay for it now, but it was free for me at the time I got it so I may be grandfathered in. Probably not open source ... yada
Still it has served me well keeping 5 linux machines synced on 2 Gmail accounts.

Following my initial post on Sunday 21 April 2019, the gdrive problem has now been fixed following today's update to Dolphin kio-gdrive.

Many thanks developers and to fellow Neon users who responded to my post.

Seems the issue is back. Been getting "Unable to create io-slave. klauncher said: Error loading '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/gdrive.so'." for the past few weeks. Just upgraded to the lastest released package yesterday, with the same error.

More of the error:

david@kde-neon:~$ kioclient5 exec gdrive:/
kf5.kio.core: couldn't create slave: "klauncher said: Error loading '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/gdrive.so'."
kf5.kio.widgets: KRun(0x55df32e5c220) ERROR 173 "Unable to create io-slave. klauncher said: Error loading '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/gdrive.so'."

Problem is still there. Latest KDE Neon here.

Problem is still there on my system too. Was working just a few days ago. I do updates daily.

I am also getting this in 19.08 in OpenSUSE Tumbleweed.

Has anyone worked any solution out yet?

(apart from the reboot / logout / recreate account, etc suggestions, which don't seem to work)

I have problem also

Maybe it needs a rebuild?

Well, the bug in question was for version 1.2.5 and was fixed but I am encountering the error on 1.2.7. Is the reason still valid?

The symptom looked similar, so I was wondering if the resolution would also be similar.
