curl-config uses krb5-config, but libcurl4-openssl-dev only Suggests libkrb5-dev

[Mekk]

Attempt to run curl-config on the system, on which libkrb5-dev is not installed, results in error

   /usr/bin/curl-config: krb5-config: not found

At the same time, libcurl4-openssl-dev only Suggests libkrb5-dev.

Either curl-config should gracefully handle lack of krb5-config, or the dependency should be stronger.

Are you running curl-config with particular arguments? When I install libcurl4-openssl-dev on a fresh 18.04 system, running curl-config with no arguments gives no errors.

IIRC I used
   curl-config --libs --static-libs

Considering I just supported another colleague who faced this bug, let me mention that the problem is still present (in 20.04).

Simplest example:

$ sudo apt install libcurl4-gnutls-dev # Or some other variant
…

$ curl-config --static-libs
/usr/bin/curl-config: 1: krb5-config: not found
…

It is easily fixed by

$ sudo apt install libkrb5-dev

but once more: considering curl-config uses krb5-config, libcurl*-dev should depend on libkrb5-dev.
