Hello, I want to install liburcu-dev:i386 and liburcu-dev:amd64 simultaneously on my x86_64 machine. I cannot do that using 'apt install' as either installation removes the other.
1. I went through https://wiki.debian.org/Multiarch/Implementation. 2. I fetched .deb files for both, extracted them using, dpkg-deb -R liburcu-dev_0.9.1-3_amd64.deb rcupackage_amd64 dpkg-deb -R liburcu-dev_0.9.1-3_i386.deb rcupackage_i386 3. Added 'Multi-Arch: same' to DEBIAN/control file for both packages. 4. Re-packaged them using, dpkg-deb -b rcupackage_amd64 rcupackage_amd64.deb dpkg-deb -b rcupackage_i386 rcupackage_i386.deb 5. Installed both using, sudo dpkg -i rcupackage_amd64.deb; sudo apt install -f sudo dpkg -i --force-overwrite rcupackage_i386.deb; sudo apt install -f The overwrite was done for files in /usr/share/doc/liburcu-dev/examples/ and file /usr/include/urcu/config.h. In this way, I was able to install both and use them for what I wanted. But how to avoid the clash of files? I understand that we have these different names usr/lib/i386-linux-gnu and usr/lib/x86_64-linux-gnu.
