libmpc-dev: unmet dependency

[robbwu]

Hi there,
Not sure if this is the right place to ask for help.
I tried to install a specific package libmpc3-dev but encountered the following error:

Code: Select all

$ sudo apt install libmpc-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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:
 libmpc-dev : Depends: libmpc3 (= 1.0.3-1+b2) but 1.1.0-1~mx17 is to be installed
E: Unable to correct problems, you have held broken packages.

Any help?
Thanks in advance
Best regards

The likeliest reason for this is that you, at some point, installed a package from the MX Test repository - either libmpc3 directly or another package that pulled libmpc3 in as a dependency.

Since libmpc-dev must be exactly the same version as libmpc3 you are getting this error. Install libmpc-dev from the Test repository using the MX Package Installer. You'll have to uncheck the checkbox that hides library & developer packages and Refresh the list to see it.

Yes sir, you are spot on. Thanks!
Problem seems to be resolved by installing libmpc-dev from MX testing repo.

Cheers,
