Installing libboost-dev on Ubuntu 12.04:
System is offline due to unchangeable circumstances, so I have to download libraries and install manually using 'dpkg'.
Ubuntu package repository shows that libboost-dev for 12.04 is 18.104.22.168, and relies on "libboost1.46-dev"
I have another system, online, with identical setup, that I queried to find out which libboost-dev package is installed. This confirms the 1.48.02:
~$ dpkg -l libboost-dev Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-===========================================-===========================================-====================================================================================================== ii libboost-dev 22.214.171.124 Boost C++ Libraries development files (default version)
So I downloaded the two packages, copied them manually to the offline system,
and tried to install:
~$ sudo dpkg -i libboost* dpkg: considering removing libboost1.48-dev in favour of libboost1.46-dev ... dpkg: no, cannot proceed with removal of libboost1.48-dev (--auto-deconfigure will help): libboost-timer1.48-dev depends on libboost1.48-dev (= 1.48.0-3) libboost1.48-dev is to be removed. dpkg: regarding libboost1.46-dev_1.46.1-7ubuntu3_amd64.deb containing libboost1.46-dev: libboost1.48-dev conflicts with libboost1.46-dev libboost1.46-dev (version 1.46.1-7ubuntu3) is to be installed. dpkg: error processing libboost1.46-dev_1.46.1-7ubuntu3_amd64.deb (--install): conflicting packages - not installing libboost1.46-dev (Reading database ... 217276 files and directories currently installed.)

'dpkg' first considers replacing what seems to be the installed 1.48, but then can't because so many things depends on it. It then says "libboost1.48-dev conflicts with libboost1.46-dev".
My online system shows that both packages are installed, but my offline system won't install, and that the package has only been unpacked:
~$ dpkg -l libboost-dev Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-===========================================-===========================================-====================================================================================================== iU libboost-dev 184.108.40.206 Boost C++ Libraries development files (default version)
What is wrong, that dpkg cannot install this?
