Hi,everybody ! Everytime I boot my Ubuntu an error window appears on my screen (attached a screenshot bellow) . I tried to report error ,but received nothing . Also I deleted the content of /var/crash directory as I was adviced to do on another forum,but that didn't work either. Could someone explain me what's this error in deed and how to get rid of it ? Thank you

Create another user on the system and login as that user. Same error?

Let us know.

Obviously it is a system program that is crashing...

The crash report is a flat file. You can examine it in a text editor to see what is actually causing the problem. After a bit of searching it could be a bug.

Also when I connect to a wifi network,it stays connected a whie,then the connection fails and only after restart I can connect again. I tried to study that reports,but dindn't understand a lot,something tied with dhcp service .I attached the reports bellow . http://txs.io/4vyb

With tools you can do some debugging yourself but it is really designed for the developers.

Have not played with 14.04. It looks like the command is trying to acquire an IP address for lo i.e. localhost which should fail. Post the contents of your /etc/network/interfaces file.

Without knowing anything about your wireless set up we can not say why it is only connecting for awhile.
