Question

I have tried to recompile the kernel with make command for config but this error occured:

scripts/extract-cert.c:21:10: fatal error: openssl/bio.h: No such file or directory
 #include <openssl/bio.h>

So then a i have tried install libssl-dev:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.1 (= 1.1.1b-1ubuntu2) but 1.1.1b-1ubuntu2.1 is to be installed
E: Unable to correct problems, you have held broken packages.

Can anyone tell me how can i fix my dependecies? And why do I have them broken?

Answer 1

尝试安装aptitude并使用此工具来降级 libssl-dev。

$ sudo apt-get install aptitude

在这一步之后，使用 aptitude 从 1.1.1b-1ubuntu2.1 降级到 1.1.1b-1ubuntu2

$ sudo aptitude install libssl-dev

仔细选择选项。这将解决您的问题。
