Bug#1011152: spyder: Console not starting. Spyder alerts : iPython 7.31.1 & qtconsole 5.3.0 not installed. But they are !

[RB68]

Package: spyder
Version: 5.3.0+dfsg1-7
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: epsommumule at virgilio.it

Dear Maintainer,

I upgraded Spyder 4.2.1 to 5.3 both on my main desktop PC and in a qemu client.
In both cases I encountered a problem.

The console would not start in the qemu client, Spyder alerting that iPython
7.31.1 & qtconsole 5.3.0 are not installed, even though they are ! After a
reboot I still faced the same problem.

On my main desktop (which hosts qemu), I got the same alerts...but the console
started. I tested some python code I worked on the day before, and it still
works fine. So the alerts do not prevent Spyder from functioning normally.




Here are the error messages from Spyder :

# Mandatory:
IPython >=7.31.1 : 7.28.0 (NOK)
qtconsole >=5.3.0;<5.4.0 : 5.1.1 (NOK)

I googled this, read some bug reports, some forum discussions, but did not find
any solution.
