Package: wpasupplicant Version: 2.5-2+v2.4-3+b1 Followup-For: Bug #835648 Adding : " RuntimeDirectory=wpa_supplicant RuntimeDirectoryMode=0750 " to the [Service] section of wpa_supplicant.service file fixed it for me.
The rationale behind this change is that I observed on resume /run/wpa_supplicant is there but deleted soon afterwards. This by mean of "ls -l /run". I hastily checked tmpfiles.d for tmpclean but got not further. The above change was suggested by tmpfiles.d man page.
