Good morning,

Following the public announcement regarding the vulnerability and the upgrade to version 2.0.0.9450, I encounter an error message when I launch the upgrade:

Fatal Python error: initfsencoding: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f22ac063740 (most recent call first):
Aborted
E: Sub-process /usr/bin/apt-listchanges --apt || test $? -lt 10 returned an error code (1)
E: Failure running script /usr/bin/apt-listchanges --apt || test $? -lt 10

Looking around a bit, I saw that I had python 2.7 and python 3.7 in /usr/local/lib.
Should I "uninstall" Python 2.7?
Do you have any suggestions for resolving this error message?

Thank you in advance.

Code: Select all

python3
Python 3.7.3 (default, Jan 22 2021, 20:04:44) 
>>> import locale
>>> locale.getpreferredencoding()
'UTF-8'
>>>

Can you try this on your machine to see if getpreferredencoding works?

Thank you for your response.
However, I absolutely cannot launch Python 3...

Code: Select all

Does this work?

Code: Select all

/usr/bin/python3.7

No, still the same error...
We had no problems during the migration from 1.8 to 2.0.

Wapt doesn't use Python; we use a virtual environment, so it's surprising:

In this case, it's the local Python installation on your machine that's no longer working:

In your export, do you have any references to Python?

Code: Select all

export|grep -i python

Hello,
thanks for the tip.
After making some mistakes, restoring the hosted VM, uninstalling and then reinstalling Python, the upgrade worked, although I'm still getting the same Python error...
Anyway, the migration to version 9450 is OK.

Have a good day.
