The openclash prompt of openwrt [Update failed, please confirm that the device has enough flash memory space and try again]

I searched on the Internet, and the problem should be "unable to download the kernel update package from the Internet" or "unable to recognize the version number of the kernel" (openclash will go to github to download the kernel, and github will intermittently convulse, and the download cannot be completed automatically when the convulsion occurs.)

Solution: Download manually (I only got the DEV kernel, TUN and Meta did not move) --> Upload to the router --> Unzip --> Go back to the openclash interface to update the configuration file

1. Find the corresponding architecture installation package in the Dev kernel release page

• Dev kernel download : https://github.com/vernesong/OpenClash/releases/tag/Clash   (mine is clash-linux-armv8.tar.gz)

 2. Upload to /tem/upload/directory

 3. Copy to /etc/openclash/core/ and decompress

Copy --> Enter /etc/openclash/core/ --> Unzip --> Set read and write permissions

cp /tmp/upload/clash-linux-armv8.tar.gz /etc/openclash/core/

cd /etc/openclash/core/

tar -zxvf clash-linux-armv8.tar.gz

chmod 777 clash

exit

4. Update configuration

5. Done!
