Problem
Maybe something wrong with firmware-selector.When I tried to build custom firmware on firmware-selector,I get the error below,switching versions also doesn't work(I didn't have this problem yesterday):
Unsupported package(s): button-hotplug, kernel
and the following are the software packages entered during the custom build:
luci luci-base luci-compat luci-i18n-base-zh-cn
luci-i18n-firewall-zh-cn
luci-i18n-opkg-zh-cn
vsftpd openssh-sftp-server
htop curl
ttyd luci-app-ttyd luci-i18n-ttyd-zh-cn
This is the screenshot with the error:
