The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

[Dennis Tants <tants AT uni-bremen.de>]

Hello,

we had the same problem on different linux systems.
For us the problem was, that the CAT Tool can't write the file to
"/etc/NetworkManager/system-connections" without root permissions. So we
had to use sudo to be able to atleast write the file. Afterwards we
would just edit the corresponding permission line, to match the system
user. Reboot the system (just to be sure) and eduroam could be used.

Yours sincerely,
Dennis Tants
