Estou com problemas ao instalar o timeshift pelo yay, atualizei o locale-gen e ele continua a não reagir a localização, e o AsyncTask.vala não encontro e possivelmente nem existe, alguém conseguiu resolver este problema?

tenta pelo git hub GitHub - wesaphzt/timeshift at patch-1
pra corrigir esse problema do Async Task você tem que alterar uma pequena linha do AsyncTask.vala nano /home/user/timeshift/src/Utility/AsyncTask.vala
alterar o “public AsyncTask(){” por “protected AsyncTask(){” depois é so da make all e depois sudo make install
