Title:
Filenames with spaces not accepted when connecting to certificate-
authenticated wifi
Status in network-manager-applet package in Ubuntu:
Fix Released
Status in network-manager-applet source package in Bionic:
Fix Released
Bug description:
* Impact
Using an authentification certificate with a filename in its name is not
possible
* Test case
- connect to a wpa wifi needing a certificate
- name the certificate to include a space
- try to use that said certificate
it should be possible to use it
* Regression potential
the change is on the function dealing with the filename/uri for certificate,
make sure those keep working on different locations with names including spaces
or not
*******************
This bug was encountered on a fresh install of Ubuntu 18.04.1 LTS
When connecting to a certificate-authenticated wifi network (WPA/WPA2
Enterprise, authentication TLS) for the first time, the "Wi-Fi Network
Authentication Required" dialogue is displayed, prompting the user to
select their CA and user certificates.
Unexpected behaviour: If any of the files have spaces in their
filenames, after choosing them in the file picker the field is
highlighted by a red box, and the 'Connect' button is greyed out.
This is depicted in the attachment network-authentication-red-box-
spaces-filename.png
There is also no explanation offered for why the red box highlight is
present - no tooltip, no help from pressing F1, no popup, and as far
as I can find no logs.
If you move/rename the file, so there are no spaces in the filename,
the problem is worked around.
The problem is not present on the edit connection dialogue; filenames
with spaces are acceptable there.
The problem was also not present on Ubuntu 16.04, and users who
upgrade from 16.04 to 18.04 will find their connection keeps working.
It is only when creating an entirely new connection (or after
forgetting the connection and recreating it) that the problem dialog
appears.
