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:
 libtiff5-dev : Depends: liblzma-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

said "depends liblzma-dev", then I tried to

$ sudo apt-get install liblzma-dev

but error too, here is the output :

Just had the same issue in Ubuntu 20.04.3 with a newer version of that package.

The following packages have unmet dependencies:
   liblzma-dev : Depends: liblzma5 (= 5.2.4-1) but 5.2.4-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

Fixed it by downgrading the required dependency and installing the version it's asking for.

apt install liblzma5=5.2.4-1
