Why do I get error(s) about permissions ?

One of the very first steps before actual installation takes place, is to do a check to see if certain files and directories can be read from and written to by the "web-user" (the username used by your webserver).
Failing to have appropriate access (read, write, execute) to these files and directories, will prompt you to fix it before continuing with the installation.

You will see the number of error(s) found, and exactly what file/directory each error is related to.

Once the permissions are as expected, you will be able to continue installation.

You can either set/change permissions using f.ex. your FTP-program (if you install on a server that's hosted by your ISP), and/or if you have terminal access (either directly or using f.ex. telnet) using these commands:

cd /var/www (Note: may be different on your box, depending on what you "doc_root" is set to)
chmod 777 ampjuke-0.6.3
cd ampjuke-0.6.3
chmod 777 tmp
chmod 777 covers
chmod 777 lastfm
chmod 777 db*.*
