Je vais commencer par dire que j'ai configuré un fichier conky et que je l'ai fait fonctionner, mais lorsque j'ai ajouté des anneaux lua, celui-ci a fonctionné sans redémarrage. Une fois redémarré, les anneaux ne démarraient plus. J'ai reçu le message d'erreur dans le titre, voici mon script conky

Clock Rings by Linux Mint (2011) reEdited by despot77
This script draws percentage meters as rings, and also draws clock hands if you want! It is fully customisable; all options are described in the script. This script is based off a combination of my clock.lua script and my rings.lua script.
IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement on line 145 uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num>5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num>3; conversely if you update Conky every 0.5s, you should use update_num>10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.
To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):

s'il vous plaît, aidez, qu'est-ce qui ne va pas?
J'ai eu le même problème en 16.04. J'ai résolu avec Sudo apt install conky-all -y.
J'espère que cela fonctionnera pour vous!
dans la fonction conky_clock_rings() ajoutez le code suivant après value=tonumber(str)
if not value then
value=0
end
Vous pouvez résoudre votre problème en ajoutant ces lignes à votre script lua:
str=string.format('${%s %s}',pt['name'],pt['arg'])
if str=='${time %I.%M}' then
str=conky_parse('${time %I}')+(conky_parse('${time %M}')/60)
elseif str=='${time %M.%S}' then
str=conky_parse('${time %M}')+(conky_parse('${time %S}')/60)
else
str=conky_parse(str)
end
value=tonumber(str)
if ( value == nil ) then value = 0 end
pct=value/pt['max']
C'est ma première fois avec Lua mais j'ai résolu mon problème:
