openSUSE has issued an advisory today (August 2):
The issue is fixed upstream in 2.2.10 and 3.0.17:
Mageia 8 is also affected.
Fixed upstream in 2.2.10 and 3.0.17
3.0.17 pushed to cauldron
2.2.10 pushed as well to testing_updates for mga8
Hopefully the move from 2.1.2 to 2.2.10 won't create issues.
Fixed upstream in 2.2.10 and 3.0.17 =>
Installed Core components.
One of these indicates that sphinx is used to handle or generate local documentation.
Some sphinx components are already there but sphinx-2.3.2 can be installed.
Could not locate any jupyter_core/docs - maybe that is something extra to download. Once jupyter_core/docs is established the web documentation can be generated from that folder using `make html linkcheck`.
A browser would find it at e.g. file:///my/projects/jupyter\_core/docs/\_build/html/index.html
Had a stab at starting python3-jupyter-client - not successful.
$ rpm -qa | grep jupyterlab
Tried to update via qarepo/MageiaUpdate but failed.
$ ls <localrepo>/x86_64
Sorry, the following packages cannot be selected:
- python3-jupyterlab-2.2.10-1.mga8.noarch (due to unsatisfied python3.8dist(jupyterlab-server)[>= 1.1.5])
$ urpmq --provides jupyter-jupyterlab-server
Looks like jupyter-jupyterlab-server will have to be updated too.
Installed it with
jupyter-jupyterlab 2.2.10 1.mga8 noarch
python3-jupyterlab 2.2.10 1.mga8 noarch
A new tab opens in Firefox.
Opened a previously saved notebook. Opens fine.
Updated OK this time.
Started jupyter-lab from a terminal and opened a file tab in Firefox at the suggested URL. No real idea what was going on but pasted a python script into the input panel and clicked on run. That worked - Eratosthenes sieve over the range 1-300.
Saved the notebook and closed the server with Ctrl-C. Could not find the file in user directory or .local/share/jupyter.
Started it again and exported the notebook page as HTML. That appeared in the Downloads directory and could be displayed in the browser directly, code and results.
So, something is working but taking this any further would require rather too much time.
Far from satisfactory - giving this a tentative OK.
Nobody's come forth asking for more, so I'm validating.
An update for this issue has been pushed to the Mageia Updates repository.
