How to install packages of 16.04 to 17.10

  • 772

For some reason, I have to install some packages of Ubuntu 16.04 to Ubuntu 17.10. I've tried to apt update && apt install pkgname but there are always some dependency issues.

What I'm trying is that I get the source of some package with the command apt source pkgname.

I've found that I got three things:

pkgname.dsc
pkgname.orig.tar.gz
pkgname.debian.tar.xz

The .dsc file seems to contain some information of pkgname, the .orig.tar.gz file is the source code, but I don't know what the .debian.tar.xz file is.

For example, to install libpcl-dev, I did things as below:

apt source libpcl-dev && tar xzvf pcl.orig.tar.gz && cd pcl && mkdir build && cd build && cmake .. && make install && make.

It seems to work but I can't get what I need, which means that there isn't a file named libpcl-dev in /usr.

    Installing the binary (.deb) package of libpcl-dev from the 16.04 repositories on a 17.10 system is difficult, if not impossible, due to its many dependencies, some of which have to be installed from 16.04 and may conflict with packages already installed from 17.10.

    However, building the source package from 16.04 on a 17.10 system is possible, because all the build dependencies are available in 17.10.

    First make a directory to work in

    mkdir ~/libpcl
cd ~/libpcl

    Get the source package

    wget http://archive.ubuntu.com/ubuntu/pool/universe/p/pcl/pcl_1.7.2.orig.tar.gz
tar xf pcl_1.7.2.orig.tar.gz
cd pcl-pcl-1.7.2
wget http://archive.ubuntu.com/ubuntu/pool/universe/p/pcl/pcl_1.7.2-14build1.debian.tar.xz -O - | tar xJ
debuild

    Probably when you run debuild you will get a "command not found" telling you to install devscripts; install it and run debuild again. Now it will complain that some build dependencies are missing; install them and run debuild again, and now the build should be successful (errors about debsign can be ignored). You will have some .debs in your ~/libpcl directory, which you can install as usual.

    Warning: if some bugs, including security issues, are found in this version of PCL and a fixed version is released in 16.04, you will not automatically get it; instead you must repeat the above process with the new source package.
