I think this might be late since I was using Ubuntu 18.04 until recently when I upgraded to latest version 19.04
Tried to install Mcuxpresso IDE I encountered some dependency errors but managed to solved it. I had already replied to question about it but decided #to write main post about it.
This is what I did (installed the dependencies)
(my laptop is 64 bit)
sudo apt install libusb-1.0-0-dev
sudo apt install dfu-util
download amd64 build of icu 60.1-1
install the package (open terminal from the file location)
sudo dpkg -i libicu60_60.1-1ubuntu2_amd64.deb
sudo dpkg -i libwebkitgIDEIDEtk-1.0-0_2.4.11-4_amd64.deb
install IDE(open terminal from file location)
sudo chmod +x ./mcuxpressoide-11.0.0_2516.x86_64.deb.bin
After this you should home and dry
Everything worked well.
If you have any problem you can reply to this post.
