regarding installation error in Mininet-wifi : E: Package 'python-matplotlib' has no installation candidate

[Alka Sharma]

Respected sir 

Most humbly it is stated that I am facing an installation issue inside mininet-wifi folder when I try to install W( Wireless Dependencies)

when I run -----

isha@isha-Inspiron-15-5518:~$ cd mininet-wifi
isha@isha-Inspiron-15-5518:~/mininet-wifi$ util/install.sh -W

******************************************************************************

I face an error 

E: Package 'python-matplotlib' has no installation candidate

*********************************************************************************

I tried many ways of removing it  like  ---sudo python2 pip get-pip.py  to add installation candididates

but the above error persists

also sir due to this error I am facing errors like 

****************************************************************************

Usage: mn [options]
(type mn -h for details)

mn: error: no such option: --wifi

******************************************************************************

Sir earlier I used Mininet wifi on some other system but no such issue was there but on my second system I am facing these errors 

my pip version is 

isha@isha-Inspiron-15-5518:~$ pip --version
pip 22.0.3 from /home/isha/.local/lib/python3.8/site-packages/pip (python 3.8)
isha@isha-Inspiron-15-5518:~$ pip3 --version
pip 22.0.3 from /home/isha/.local/lib/python3.8/site-packages/pip (python 3.8)
isha@isha-Inspiron-15-5518:~$ python  --version
Python 2.7.18
isha@isha-Inspiron-15-5518:~$ python3  --version
Python 3.8.10
isha@isha-Inspiron-15-5518:~$

Kindly help me to rectify the issue

Thanks and regards

You can either try python3 or use the source for python-matplotlib via apt. Not sure why you mentioned pip.
