Hi, I'm trying to install Zotero Beta (with the internal PDF reader option) on my Ubuntu machine, but thus far without success. I downloaded the build (https://www.zotero.org/support/dev_builds) and followed the installation instructions for Linux here: https://www.zotero.org/support/installation. However, plugging the line "ls -s zotero.desktop ~/.local/share/applications/zotero.desktop" into the terminal doesn't do anything.
Any suggestions of what I'm doing wrong or of alternative approaches will be appreciated!
