Circos installation on Ubunt 18.04

[Junhao Wen]

Hi, 

I have spent days installing Circos on my Mac (Ventura) and Ubuntu (18.04), but neither worked... I followed the instruction here: http://circos.ca/documentation/tutorials/configuration/installation/ 

Sorry to ask the silly question (I am not expert on Perl): Is the software still maintained? This is such a wonderful software, but it seems to me that all info is out-of-date...

Specifically for my Ubuntu installation, I got stuck at the first step: 

sudo apt-get install libgd2-xpm-dev                                                                                               
[sudo] password :
Reading package lists... Done
Building dependency tree      
Reading state information... Done
E: Unable to locate package libgd2-xpm-dev

I then found this post: https://groups.google.com/g/circos-data-visualization/c/cj_SIVFyPzY/m/VsUzPHaoBQAJ

But the download link did not work...

Thanks
