Как определить, включен ли Num Lock или Caps Lock в RHEL 6.6?

При установке google-chrome я также столкнулся с сообщением об ошибке.

dpkg: dependency problems prevent configuration of google-chrome-stable:
google-chrome-stable depends on libappindicator1; however:
Package libappindicator1 is not installed.

Затем я попробовал установить libappindicator1, что опять привело к следующему сообщению :

root@Am-I-Helpful:~/Downloads# apt-get install libappindicator1
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libappindicator1 : Depends: libdbusmenu-glib4 (>= 0.4.2) but it is not going to be installed
                    Depends: libdbusmenu-gtk4 (>= 0.4.2) but it is not going to be installed
                    Depends: libindicator7 (>= 0.4.90) but it is not going to be installed
                    Recommends: indicator-application (>= 0.2.93) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Он попросил меня запустить apt-get -f install, чтобы продолжить установку. Итак, я выполнил команду :

root@Am-I-Helpful:~/Downloads# apt-get -f install
