Conky is working but is no longer able to support old style of configuration files in Conky Manager
~/.conkyrc in home folder is now ~/.config/conky/conky.conf and uses a ‘lua style’ language structure
(similar structure to conky .lua script files but different function)
conky changed syntax style years ago and has done a good job of maintaining backwards compatibility
conky-manager author appears to have stopped developing and maintaining package beyond Ubuntu 14.10 - Conky Manager – TeejeeTech
updated configurations should have been created by current maintainers at Launchpad (Code : conky-manager) but last sign of activity there is from 2016
and no sign of any published conky configurations to be able to convert
best i could find for an old Gotham theme was this:
http://drive.noobslab.com/data/conky/Gotham/gotham-noobslab-gmo.zip
this is the old style .conkyrc
running the conversion script ./convert.lua .conkyrc conky.conf changes it to conky.conf
but the height and width values are wrong - screenshot
and there is an error message
conky: Invalid value ‘conky’ for setting ‘own_window_type’. Valid values are: ‘normal’, ‘dock’, ‘panel’, ‘desktop’, ‘override’.
so configuration needs to be edited manually for working conky.conf
if the convert.lua script is not working for you, use these examples and the style guidelines from conky wiki to edit the configuration file manually
if new configuration file is saved to default location and name ~/.config/conky/conky.conf
conky can be started just by terminal command conky
and conky-manager is no longer required
