Can't save openvpn connection (connection.gateway-ping-timeout: can not set property value 37892016)

[Yuriy Vidineev]

Hello
I have relatively simple openvpn connection config

[connection]
id=developer-vpn-la
uuid=3e6fc95d-0bc0-4118-a00a-7c6f3852c2fd
type=vpn
gateway-ping-timeout=71
permissions=
secondaries=

[vpn]
ta-dir=1
fragment-size=1400
connection-type=password-tls
password-flags=1
remote=some-server
cipher=AES-128-CBC
comp-lzo=yes
cert-pass-flags=4
port=1194
mssfix=yes
username=adept
ca=/home/adept/ownCloud/documents/openvpn/ca.crt
cert=/home/adept/ownCloud/documents/openvpn/adept.crt
key=/home/adept/ownCloud/documents/openvpn/adept.key
ta=/home/adept/.local/share/networkmanagement/certificates/ta.key
service-type=org.freedesktop.NetworkManager.openvpn

[ipv4]

method=auto

[ipv6]

dns-search=
method=auto

I want to add 'never-default=true' option via GUI (KDE) but it can't be saved. Error in logs:

nmcli works as expected
sudo nmcli connection modify uuid 3e6fc95d-0bc0-4118-a00a-7c6f3852c2fd ipv4.never-default true

Status changed to 'Confirmed' because the bug affects multiple users.

I receive the message "connection.gateway-ping-timeout: can not set property: value "xxxxxxxx" of type 'guint' is invalid or out of range for property 'gateway-ping-timeout' of type 'guint'" almost on every change of network connection properties

Hi there,

the problem is even worse. Even the simplest network connections fail most of the time, as the value to be set for connection.gateway-ping-timeout varies randomly.

Steps to reproduce the problem (almost) consistently on Kubuntu Xenial are:

# Right-click systray/Networks
# Click Configure Network Connections
# In the Connection Editor, click "Add+".
# Click Wired Ethernet.
# Click OK
# If the connection really get added, you've been lucky: A plausible number was randomly set for connection.gateway-ping-timeout.
# Either retry from step 3 until adding fails or edit your new connection, change the name and click OK. The most tries I ever needed to get the error message was 3 times.

And please take a closer look at the config of the original bug reporter: "connection.gateway-ping-timeout=71" ist explicitly set, but NM tries to set a ridiciously large value which is not in the original config!

Regards,
Jochen

I've just found bug #1569674, which already has a link to an fixed bug in upstream. This bug seems to be a duplicate.

Thanks, Jochen! I think you're right and it's a duplicate
