I am currently learning how to use VASP and was looking at how to get the DOS plots. I have been recommended to use P4VASP but due to some reason I am not able to install it on my Ubuntu 20.04. When I try to use sudo to install the said package it says no package p4vasp found. And I think that the older website has also been depreciated http://p4vasp.at/.

Am I required to work with Ubuntu 18.04 only? Or is it somehow possible that p4vasp is no longer working or something. Thanks

    $\begingroup$ As far as I know, everything I tried, and everything tried by several friend always failed. You can not run p4vasp code on 20.04. Toomany packages have been abandoned. Welcome to Academia. $\endgroup$

The source code is still available on Github, though it hasn't been updated for nearly 4 years. While the project seems to be abandonded, you should be able to compile from source. I don't suspect the change from Ubuntu 18 to 20 would make it unable to compile, but there probably is not a readily installable version for Ubuntu 20.04.

The P4VASP code is one of the easiest visualization tools for VASP outputs that I have been using. From your question, I understand that your system can't find the p4vasp executable file which can be solved by adding its path to the .bashrc file in the home folder. However, there are a lot of visualization tools that offer higher quality and more control of VASP output plots. I recommend using VASPKIT to extract data from VASP outputs, and then you can use XMGRACE or GNUPLOT to plot the graphs. You can check this website that contains some GNUPLOT scripts for high-quality DOS plots. I recommend also checking this thread which I believe will be very useful for you.

    $\begingroup$ Unless I'm misunderstanding their post, they seem to have an issue even installing p4vasp, rather than accessing it after installation. $\endgroup$

py4vasp is also used as an interface for VASP. You can install p4vasp by using pip pip install py4vasp Please check p4vasp for more detail.

    $\begingroup$ Note, p4vasp is a different program than py4vasp. While the developer of p4 has contributed to py4 at least once, they have largely been developed separately and p4 seems to be defunct. $\endgroup$
