Hi, I was trying to install uGet downland manager from source while I got this error message. "Package requirements (gtk+-3.0 >= 3.4) were not met: No package 'gtk+-3.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GTK_CFLAGS and GTK_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details." How can I fix this? With thanks, Muntasim-Ul-Haque |
