I am running Xubuntu 10.10 and I need to install Adobe Acrobat Reader on it. I went to Adobe's site and downloaded the file. I ran chmod +x on the downloaded file. I then ran the executable file and it said, "Extracting files, please wait." Then it said, "Enter installation directory for Adobe Reader 9.4.2" showing /opt as the default directory. However, when I press enter I get, "Error: Cannot write to directory /opt"
What is wrong here and how can I fix it?
Thanks in advance.
