Please check the confirmation dialog on your device
Solution 1
This usually happens when you miss accepting the RSA Key Notification at first.
Best would be to reset the setting.
Do as follows:
Switch OFF
Developer's option
.Under Developer Setting, Tap on
Revoke USB Authorization
Switch ON Developer's option
Enable USB Debugging
, and you would see RSA Key Notification on deviceYou should immediately see the above notifiaction.
Select
Always allow from this computer
and Ok.
To avoid further denial.
The link mentioned in your question should also work.
Might be some issue.
Update:
This might also be an Issue with your adb
binary version.
Check adb
version using:
$ adb version
Android Debug Bridge version 1.0.31
If you are using an older version please update.

I had the same problem. I have two different Linuxsystems on my computer. The installation on MX-Linux 19.3 xfce was very easy and working after a short time. The installation on Mint 19.3 Cinnamon would not work. All instructions i found in google didn't solve my problem. After deleting the files adbkey and adbkey.pub in my directory, i didn´t get these files, when i followed the instructions. I got always the status "device unauthorized" and did not get the "confirmation dialog on my device". Then i had a divine inspiration. In a console i gave me root permission via su and started there droidcam. I imediately got the confirmation dialog on my smartphone and the driodcam was working fine. The files adbkey and adbkey.pub are now in the directory /root/.android.

I am trying to connect adb device and it showing "Please check the confirmation dialog on your device" ..but there is no adb confirmation(rssi) dialog.
Same adb setup for other device. I checked with https://stackoverflow.com/a/23086501/2624806 and some other post as well. But it's not working for me.
Any suggestion!

Saurabh Meshram over 9 yearsI am able to reproduce the issue, and above step work fine. Maybe you can try restarting the device, plug-unplug and Restart ADB process. You basically need the Step 4 Notification to be accepted.
