Not crucial information
While testing the website I found some issues that are happening in the real website but not on the local website. Some context: i test out my website on windows and only then rsync everything to the actual server which runs in Debian. The core of the problem is that sudo apt install hugo does not install the latest version, and becomes not fully compatible with the PaperMod. To fix this issue we have to download the latest version from the git repo.
Probably important information
First of click here to find the latest hugo verion, then find the .deb package and copy the link to it. Next, go to your debian terminal and write wget link-that-you-copied, this should download the .deb file. Lastly just write sudo dpkg -i your-hugo-file.deb.
Success?
I hope this is of help for fellow not-very-competent linux users such as myself!
