Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.
If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart. Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit. If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'. I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding. ** Changed in: network-manager (Ubuntu) Importance: Undecided => High ** Changed in: network-manager (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1584276 Title: network-manager crashes when changing wireless access points Status in network-manager package in Ubuntu: Invalid Bug description: After upgrading to 16.04 LTS, whenever trying to switch wifi access points (APs), network-manager "crashes" -- meaning that the applet no longer displays available APs and in their stead is a message "device not ready." In case it helps, here are the wifi script results: https://dl.dropboxusercontent.com/u/13392425/wireless-info.txt. Note that this is bug different and distinct from Bug #1574347 (wifi dies on wake from suspend), and the reported fix for that bug does not help at all.
