I'm using Manjaro, The installation failed with the error /usr/bin/ld: /usr/lib/libQt5Qml.so.5.
I've tried to uninstall but it also gives an error (unfortunately, I didn't save that)
I tried to open KDE settings but it crashed, I used the command systemsettings to know what was wrong with it, it was something like this: missing /usr/lib/libstdc++.so.6 required by GLIBCXX_3.4.32 in /usr/lib/libQt5Qml.so.5
I'm sorry for not saving the exact errors. It's not that different
after rebooting the laptop SDDM does not open and the problem is solved by using tty to install libtool, gcc and gcc-libs
