Jupyter noteboook keep reconnecting to kernels since Nov. 5th, 2018 #462

Closed ShamrockLee closed 5 years ago

ShamrockLee commented 5 years ago

I use Linux Mint 19 (Ubuntu-based) and sudo apt install jupyter-notebook -f several weeks ago. It had been working well until recent days. The blue "connecting" box start flashing right after a notebook is opened and the starting the kernel disappeared no matter if I use Python, Julia, or GNU Octave kernel. The terminal shows something like this:

This makes it unable to use. Hope there is a solution or a work-around that can make it work again.
