Is there a ONVIF Device Manager alternative for Ubuntu 16.04LTS
xeoma has a tar.gz installer. 32-bit and 64-bit. It only has 1 file and worked straight out of the box for me.
Mind though: it is payware (and monthly even, if I read the license correctly).
Open source and free: zoneminder They have a warning: don't use our repos since they are out of date and to use their PPA. Pity it has not been updated to 16.04 so is out of date as well ( :P ).
You can try Lingodigits' ONVIF Device Tool, has Ubuntu 16.04 64bit version ONVIF Device Tool passed ONVIF Client Test Tool v16.01 and free to download.
