NetworkManage cant connect wifi unless nm-applet is started

[camilova]

Hi,

I use elementary OS 5.1.7 Hera, and I use Git.
I have installed libsecret to be used with git to remember my credentials.

After installing libsecret I can not anymore connect to new wifi networks (previously saved wifi works well). All is working with wifi network interface, I test firmware missing, package missing and seems to be ok.

After some research I found this on Arch Linux forum:
https://wiki.archlinux.org/index.php/Talk:NetworkManager#Explain_that_encrypting_passwords_requires_nm-applet_(or_equivalent?)_to_be_running

The problem, as I understand is that NetworkManager wants to get credentials but it can not after installing libsecret, the only way that it can is starting first the nm-applet. I dont understand very well why but I wrote this report to help anyone with same problem or even to known if this is a bug. In effect, it is like nm-applet acts as brigde to get credential through libsecret or something like this.

Steps to Reproduce:

• Install fresh Elementary OS
• Conenct to any wifi (all will work normally)
• install git and libsecret
• configure git to use libsecret as the credential manager (I dont known if this were relevant)
• reboot
• try to connect to a new wifi that needs a password

The result should be that you can't connect and password prompt never is presented.

The Solution:

• open terminal and start nm-applet
• a new orange icon will appear on systemtray
• try to connect to the a new wifi
• password prompt appears and all works perfect
• then stop nm-applet and try to connect to new one wifi, this will not work again.

Viewing the /var/log/syslog I see while trying to connect:

What ends to be the way to solve this for me was researching about the line No agents were available for this request. and I understand this as "it cant find the credential manager" ???

Then, could it be a bug on elementary (or ubuntu, or linux wide)?
