Copying files in Dolphin using admin:// is mindbendingly slow

Help
1

I created a new user profile because I wanted to split off a project to it’s own space.

I tried to copy some files over from the current, logged in profile to the new one using Dolphin.

First it tells me :

“Acting as Administrator - Be Careful”

OK, Mum.

I selected folders, dragged them over and got 60mb copied in a minute before it popped up another request for the password.

After another minute it popped up another password request and I cancelled the operation as it hadn’t even made 100mb,

This is with an nvme sdd. I copied the files to a new folder, zipped the folder and used cp to copy it.

Is there a method of making it work at the speed of using cp?

I’m told it’s something to do with the admin:// protocol

How can I circumvent this is the future please?

+1 I was just copying from a local SSD to another local SSD partition. After an hour of waiting for the copy and several forced re-authentications where it just stalled, I jumped into terminal and su, and did a cp…which completed so quickly I used dolphin to double-check the files copied at all.

How is it that 5 seconds of file copies take more than an hour with Dolphin? And should privilege escalation in Dolphin just have a warning dialog saying “this doesn’t really work for what you are trying to do?”.

Not angry…just really confused by the behavior and why it is so far different than normal expectations.

Hi - the bug report here sounds like the exact issue you’re both running into: 489926 – File transfers extremely slow when using Dolphin with admin/elevated privileges and annoying constant password popups

If you folks can add the examples you’ve seen to that bug report, that would be helpful for when it’s able to be reviewed.

Thanks!

Hmm, that may be either a Kubuntu packaging issue, or something already fixed? I’m on Plasma 6 (Fedora 41) and have the option in the View menu for any folder, and when right-clicking in root-owned folders like / and /usr:

i just went back to the LTS, everything works there as expected.

don’t think you are going to find a better file manager than dolphin.

I am using “Act as Administator” in Kubuntu 25.04. Make sure you have the “kio-admin” package installed or the action will not be available in Dolphin.
