crash

[charlie]

hey all. i just noticed during a package update that a crash happened. 
it says 'packagekit daemon' crashed. i'm running the minimal 
installation of 18.04 on a lenovo ideapad 310-15 ABR laptop. and i can't 
remember how to file a bug since it's been a longtime since i've done 
it. can someone let me know what the terminal commands are for filing a 
bug is? i think it's ubuntu-bug 'packagename'. but i need clarification. 
and yes, i've got a launchpad account.
