I am using arduino-ide2.0.0-beta.7(CLI Version:0.18.3 alpha) on Manjaro Linux and I get this error when uploading sketch to my Arduino Micro:

avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied Upload error: Error: 2 UNKNOWN: uploading error: uploading error: exit status 1

I checked other questions and tried:

sudo groupadd dialout
sudo gpasswd -a $USER dialout
sudo chmod a+rw /dev/ttyACM0
sudo usermod -a -G dialout $USER 
sudo chown root:dialout -R /dev/
ls -l /dev/ttyACM0 #can see the root:dialout 

But when I logout and get again after ls -l /dev/ttyACM0:

crw-rw-rw- 1 root uucp 166, 0 6月 13 17:06 /dev/ttyACM0

So I cannot upload the sketch. Note: I can upload sketches using sudo arduino-ide --no-sandbox , but I want to upload them from the user account.

What else can I try?

Thank you.
