I successfully used the "Ubuntu ppa" instructions at http://pharo.org/download to install Pharo Launcher on 64-bit Linux Mint 17, but doing the same on 32-bit Linux Mint 17 gives an error... $ sudo apt-get install pharo-launcher The following packages have unmet dependencies: pharo-launcher : Depends: pharo-vm-desktop:i386 but it is not installable E: Unable to correct problems, you have held broken packages. This is both without and with the second line "sudo dpkg --add-architecture i386" since I wasn't sure if it made sense to do this when already $ dpkg --print-architecture # reports... i386 The following worked without error $ sudo apt-get install pharo-vm-desktop I had a look at the package info with... $ sudo apt-get download pharo-launcher $ cp /var/cache/apt/pharo-launcher*deb /tmp $ cd /tmp $ dpkg -I pharo-launcher*deb which displayed... Architecture: any Depends: pharo-vm-desktop:386 and it seemed to me the hardcoding of :386 might be the trouble, and wondered if the following would work better for both 32-bit and 64-bit OS? Architecture: i386 Depends: pharo-vm-desktop I repackaged the deb per instructions at http://ailoo.net/2009/06/repack-a-deb-archive-with-dpkg-deb as... Package: pharo-launcher-test With a local repository set up per https://help.ubuntu.com/community/Repositories/Personal the following worked. $ sudo apt-get --allow-unauthenticated install pharo-launcher-test $ pharo However I no longer have the 64-bit LinuxMint install to test if this change is compatible. Can someone do this? cheers, Ben
