Synaptic package manager is not showing some packages after GNOME power manager error

[aviks]

Hi everybody, I had GNOME power manager error due to low disk space, so I re-installed ubuntu. Now I can't see some of the packages (most of them are '-dev' packages) in Synaptic package manager to install.
Any help?

Be sure to enable Partners repo's in the software-sources section of Synaptic and click Reload, this will add in the multiverse repositories that may have been enabled before your reinstall...
