I discovered a bug in Ubuntu 18.04 in my system which didn't let me connect to PEAP networks. On searching I found the solution was to edit the configuration file of that wireless network. But whenever I try to edit file in system-connections, I get this page:

The file opens as a blank and does not show any details. Can anyone please tell me correct command to open and edit the configuration file (with existing details showing)?

Edit: Yes I tried and failed to connect to the given Wi-Fi network which happened after I upgraded to 18.04 from 16.04. The commands I executed were:

$ cd /etc/NetworkManager/system-connections
/etc/NetworkManager/system-connections$ ls #to see list of connections
/etc/NetworkManager/system-connections$ sudo nano <network name>

Have you tried and failed to connect to KIIT-WIFI-NET? Welcome to Ask Ubuntu. – chili555 Sep 24 '18 at 01:51
In a slightly unrelated note, which bug are you taking about? If it is this one, only editing the configuration file most likely won't fix the issue. – pomsky Sep 24 '18 at 02:20
If you are editing an existing file, then most likely you misspelled it when telling nano which file to open.. – user535733 Sep 24 '18 at 04:02
Can you write down the command you are using? Also provide the directory name and file name if possible. Meanwhile, you can try sudo vi filename. – user2849789 Sep 24 '18 at 04:15

Did you run the command as root? That directory is only accessible to root, IIRC. – muru Sep 25 '18 at 02:21
