Hi
I am using the latest jupyter-notebook version (5.3.0-4) in community repo, last updated on 2018-08-06 08:26 UTC.
Before the update everything was workking fine, however after update the Kernel keeps restarting repeatedly when I create a new file.
I got the following logs
[I 21:19:23.551 NotebookApp] KernelRestarter: restarting kernel (3/5), new random ports

Am I the only one with this problem? If so, could anybody please suggest workarounds?
Thanks.

Oh!
Should have checked that first.
Thanks!

In my particular case, yesterday's updates also python from 3.6.3 to 3.7, amongst others, broke my virtual environments and couldn't start anything jupyter-related.
P.S.: It´s not only me https://bbs.archlinux.org/viewtopic.php?id=239356

I've tested and pushed an updated ipykernel package.
If your problem is fixed, please edit your first post and prepend "[Solved]" to the thread title.
