my the initial task is to install pcapy for python2.7. But I get error

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

after googling, I found three basic tips on how to solve the problem:

1 ) install libffi-dev But its already installed: libffi-dev is already the newest version (3.4.2-4)

2 ) install libpcap-dev But its already installed: libpcap-dev is already the newest version (1.10.1-4).

3 ) install python-dev

And here I get an error:

└─# apt-get install python2-dev

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python-twisted-web : Depends: python (>= 2.7.1-0ubuntu2) but it is not installable
Depends: python (< 2.8) but it is not installable
Depends: python-twisted-core (>= 11.0) but it is not installable
python2-dev : Depends: libpython2-dev (= 2.7.18-3) but it is not going to be installed
Depends: python2.7-dev (>= 2.7.18~) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Kali version:

if someone can suggest what else I can try to install pcapy, I will also be grateful for advice.

CodePudding user response：

Tells you to perform in terminal:

sudo apt --fix-broken install

You can download pcapy from the source and install it.
