Bug #12482
Updated by François ARMAND about 6 years ago
h3. Reason and workround:
The reason for this is that it may happens that your `/usr/share/ncf/tools/ncf.pyc` is more recent than the installed `/usr/share/ncf/tools/ncf.py`.
Python is just too stupid a language / vm to be used in production.
h3. Workaround
Before installation, or when the problem occures and before `apt-get install -f`, just remove `/usr/share/ncf/tools/ncf.pyc`
h3. Symptoms
During upgrade, you will see:
