Installing libgdal-dev on Ubuntu 20.04
You don't need to add apt repository for ubuntu 20.04. Just do:
-
sudo apt update. sudo apt install libpq-dev gdal-bin libgdal-dev
The Solution that worked for me is as follows
I was trying to install libgdal-dev and also had following error:
The following packages have unmet dependencies:
libgdal-dev : Depends: libarmadillo-dev but it is not going to be installed
Depends: libdap-dev but it is not going to be installed
Depends: libgeotiff-dev (>= 1.5.0) but it is not going to be installed
Depends: libhdf4-alt-dev but it is not going to be installed
Depends: libhdf5-dev but it is not going to be installed
Depends: libkml-dev but it is not going to be installed
Depends: liblzma-dev but it is not going to be installed
Depends: default-libmysqlclient-dev but it is not going to be installed
Depends: libnetcdf-dev but it is not going to be installed
Depends: libpng-dev but it is not going to be installed
Depends: libspatialite-dev but it is not going to be installed
Depends: libtiff-dev but it is not going to be installed
I have use aptitude to interactively resolve dependencies.
You can also use the GUI ncursis version only running aptitude in terminal.
It will ask to keep the current version, select n (No) and it will tell you how to resolve next. In this case it suggested downgrading packages, select 'Y' and it will install libgdal-dev successfully.
$ sudo aptitude install libgdal-dev
...
...
Keep the following packages at their current version:
1) default-libmysqlclient-dev [Not Installed]
2) libarmadillo-dev [Not Installed]
3) libdap-dev [Not Installed]
4) libgdal-dev [Not Installed]
5) libgeotiff-dev [Not Installed]
6) libhdf4-alt-dev [Not Installed]
7) libhdf5-dev [Not Installed]
8) libkml-dev [Not Installed]

Accept this solution? [Y/n/q/?] n
The following actions will resolve these dependencies:
Downgrade the following packages:
1) liblzma5 [5.2.4-1ubuntu1 (now) -> 5.2.4-1 (focal)]
2) libuuid1 [2.34-0.1ubuntu9.1 (now) -> 2.34-0.1ubuntu9 (focal)]
3) zlib1g [1:1.2.11.dfsg-2ubuntu1.2 (now) -> 1:1.2.11.dfsg-2ubuntu1 (focal)]
Accept this solution? [Y/n/q/?] Y
Now just to check run sudo apt install libgdal-dev
libgdal-dev is already the newest version (3.0.4+dfsg-1build3).
Hope this helps!!
