I think this report is similar: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=818759
The workaround there was to downgrade to version 1.0.10-1. I am currently using (just updated some minutes ago) 1.2.0-0ubuntu0.16.04.4. This does not work either. apt-cache madison network-manager-gnome reports three available versions: network-manager-gnome | 1.2.0-0ubuntu0.16.04.4 | affected network-manager-gnome | 1.2.0-0ubuntu0.16.04.3 | affected network-manager-gnome | 1.1.93-1ubuntu1 | as reported by Steve this version is also affected According to https://wiki.gnome.org/Projects/NetworkManager there are several other versions available: * 1.4.0 (2016-08-24) * 1.2.4 (2016-08-03) * 1.0.12 (2016-04-02) The related issue https://bugzilla.gnome.org/show_bug.cgi?id=766684 reports that version 1.0.4 is working, too. So reported to work are: * 0.9.8.8 * 1.0.4 * 1.0.10-1 I will check which version works for me. ** Bug watch added: Debian Bug tracker #818759 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=818759 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1573720 Title: Unencrypted private keys are insecure error reported even when key is encrypted Status in NetworkManager: Incomplete Status in network-manager package in Ubuntu: Triaged Bug description: When I enter an EAP-TLS wifi config, I get the error: "Unencrypted private keys are insecure The selected private key does not appear to be protected by a password. This could allow your security credentials to be compromised. Please select a password-protected private key. (You can password-protect your private key with openssl)" I have verified that my key is, in fact, encrypted, and I have tried using both des3 and aes256. I have also verified the password used to encrypt the key. For a while, it wouldn't even let me save the config. I managed to save it eventually, but now when I try to connect to the saved connection, I get the same error.
