libqwt-dev is not available on Ubuntu 20.04

Package 'libqwt-dev' has no installation candidate on Ubuntu 20.04. I could find a work around for libqt4-dev though. Is there a way out of it? And, can you suggest a way to dealt with the Python 2.7 dependency?

I would suggest using anaconda to create a py2.7 environment. There is also this py3 port (https://github.com/davidmatthews1uvm/EvoSoroCore) but I have not tried it myself.

This is an old post but for people who still looking for answers, this is how I managed to get it working on Ubuntu 20.04:

libqt4-dev and qt-related things can be installed via third-party PPA (so do it at your own risk). Please check out the answer here: https://askubuntu.com/questions/1234786/qt4-libqt4-in-ubuntu-20-04

libqwt-dev can be downloaded (https://packages.ubuntu.com/bionic/libqwt-dev) and installed with sudo apt install /path/to/package/name.deb. In my case, a couple of dependence were missing as well, so I had to download and install them the same way as well. The dependency list can be seen on the page.

I had the same problem (Ubuntu 20.04 focal) and I solve it by installing libqwt-headers and libqwt6abi dependencies from : (https://packages.ubuntu.com/bionic/libqwt-dev) (https://packages.ubuntu.com/bionic/libqwt-headers) using: sudo dpkg -i libqwt-headers_6.1.3-1_amd64.deb sudo dpkg -i libqwt6abi1_6.1.3-1_amd64.deb

and installed libqwt-dev after downloading it from (https://packages.ubuntu.com/bionic/libqwt-dev) using: sudo dpkg -i libqwt-dev_6.1.3-1_amd64.deb

Currently https://packages.ubuntu.com/bionic/ has error: But needed deb files are available here:
