Dear FreeSurfer experts, I am trying to perform hippocampal subfield segmentation with FreeSurfer 6. I followed the instructions found on this page: https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields which said that I first need to download Matlab Runtime. Which brought me to this page: https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime

I reach the stage where I type in curl "https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime?action=AttachFile&am..." -o "runtime.tar.gz" after which I receive the following: Die Anwendung »curl« ist momentan nicht installiert. Sie können sie durch folgende Eingabe installieren: sudo apt-get install curl

(my computer is in German, it basically says that curl is not installed and that I can install it via apt-get command). When I then type in that command and give my password, I receive:

Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut Status-Informationen einlesen... Fertig Paket curl ist nicht verfügbar, wird aber von einem anderen Paket referenziert. Das kann heißen, dass das Paket fehlt, dass es veraltet ist oder nur aus einer anderen Quelle verfügbar ist. E: Paket curl hat keinen Installationskandidaten

Which roughly translates to: reading package lists... done building a dependency tree reading status information... done Package curl is not available, but is referred to by another package. This could mean that the package is missing, outdated or available only from a different source. E: Package curl has no installation candidates.

I would be grateful for any solution suggestions! Best, Darko
