I don't think not having Synaptic is typical for Ubuntu.

Try downloading libept source and compiling it, then try installing synaptic again.

i m install vlc play after working

post the result to

cat /etc/spat/sources.list
cat: /etc/spat/sources.list: No such file or directory

Sorry, typo.

Please tell us more. What distro/version are you installing it to and what method are you using to install it?
