After the recent upgrade, when I tried to connect to my dsl, it shows like this..

Connection activation failed. (1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/5' failed in libnm-glib.

so I had to reinstall 14.10.

Some told me to reinstall the network manager when the connection is active, but how can my connection be active while I cannot connect to it ??? I could easily connect to my network in 14.10 then why is it showing such errors only in 15.04? serious problen, hope it'll be fixed soon..

  • Please check if you have pppoe installed (sudo apt-get install pppoe). It took me a while searching the net for an answer to this message before I saw (tail -f /var/log/syslog) it wasn't installed ... – user438725 Aug 11 '15 at 22:38

Do a:

sudo pppoeconf

then follow the instructions in the terminal. It will ask for a username and password and other stuff.

Just answer yes if You don't know what to answer...

  • I did this but its not working, In ubuntu 14.04 I did the same then it was working good but in 15.10 not working. any other way to fix this problem. – Shohanur Rahaman Feb 26 '16 at 13:11
