I want to install visp on ubuntu 20.04. It is mentioned that:

To install them, simply type: sudo apt-get install libvisp-dev libvisp-doc visp-images-data

But I'm getting an error:

E: Package 'libvisp-dev' has no installation candidate
E: Unable to locate package libvisp-doc

Can you please tell me how can I install this package properly? thanks.

  • [The packages](https://packages.ubuntu.com/search?keywords=libvisp-dev) are in `universe`, so enable `universe` using `sudo add-apt-repository universe` or other methods shown in the dupe and try again – muru Aug 25 '23 at 09:11
  • @mrur `'universe' distribution component is already enabled for all sources.` – Bilal Aug 25 '23 at 09:12
  • Ah I see, you're using 20.04. It seems these packages are only available for 22.04 and newer. – muru Aug 25 '23 at 09:14
