kali系统更新后的版本为

~$uname -a
Linux 4rk 5.9.0-kali5-amd64 #1 SMP Debian 5.9.15-1kali1 (2020-12-18) x86_64 GNU/Linux

进入系统后conky并未显示，通过终端启动报错如下：

~$  conky
conky: Syntax error (/home/m4k0/.conkyrc:2: syntax error near 'yes') while reading config file.
conky: Assuming it's in old syntax and attempting conversion.
conky: [string "..."]:159: attempt to call a nil value (global 'loadstring')

查资料后发现，更新后的conky对配置文件解析更加严格，以前的形如double_buffer yes的格式会解析失败，进而无法启动。更详细说明参见官方wiki

官方提供了转换脚本，可以把配置文件转换成新的可解析的格式。传送门，由于众所周知的原因，raw文件可能会下载失败，建议复制粘贴代码到本地。

备份原有配置文件，然后执行以下命令进行转换。

chmod +x convert.lua
./convert.lua .conkyrc conkyrcc
mv conkyrcc .conkyrc

注：如果出现下列问题，需要安装lua环境后再运行转换脚本，安装命令：sudo apt-get install lua5.4

./convert.lua .conkyrc conkyrcc
./convert.lua: line 3: local: can only be used in a function
./convert.lua: line 4: Usage:: command not found
./convert.lua: line 5: Tries: command not found

启动conky，熟悉的界面又回来了
