how to install boost1.61_1.61.0+dfsg.orig

I would REALLY appreciate it if someone could give me the exact command i can paste or type in the terminal.

thank you in advance for ANY help here.

There are 2 PPAs for the package. Neither support Bionic. If you contact them then they may be up for supporting the newer release.

Alternatively you can reinstall with Xenial (Ubuntu 16.04) and use the PPAs as is.

Over the course of time boost has undergone development.
For Ubuntu bionic (I assume that this is what you call "latest distro") there are packages with versions boost1.62 and boost1.65.

boost1.61 was the version delivered with Ubuntu 16.10 and 17.04 and has meanwhile be superseded.

Please tell us whether you definitely need boost1.61, or if the packages for boost1.62 or boost1.65 could also serve your needs.

(Additional remark: "boost1.61_1.61.0+dfsg.orig" is the source file name. You never want to install a source, but only the binary packages based on it.)

ok, i have ubuntu 18.4 so i guess this is "Bionic Beaver?" how do i get the binary packages for boost 1.65 and how do i install them?

There are several packages. It very much depends on the purpose for which you need them.

If you need e.g. the diagnostic support library, you can install it with the command

sudo apt-get install libboost-system1.65.1

If you want to install some foreign software that needs several boost libraries for its compilation, then maybe you best use

sudo apt-get install libboost1.65-all-dev

etc.

For which purpose do you need boost libraries?

i am trying to install my epson scanner. imagescan bundle...but it said i needed libboost.

so i'll try to install this and then try to load the imagescan again.

I downloaded these files and don't know how to install ANY of them.

/home/dave/Downloads/iscan-bundle-1.0.0.x64.deb.tar.gz

/home/dave/Downloads/imagescan-bundle-ubuntu-16.10-1.3.23.x64.deb.tar.gz

how do i do this?

thank you again for your help.

the "sudo apt-get install libboost1.65-all-dev installed without any errors.....geez

I assume that you are trying to install wrong versions of the driver.

The name of the imagescan file contains "16.10" indicating that it is made for Ubuntu 16.10. This one depends on boost1.61 libraries which were available on Ubuntu 16.10, but are not available for Ubuntu 18.04 any more.

You have Ubuntu 18.04, and so you need a different version, probably one that contains 18.04 in its file name.

I suggest that you visit http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX type in the model number of your scanner and click the icon with the magnifying glass, and do the correct selections on the following pages. Perhaps you will then end up on a page like http://support.epson.net/linux/en/imagescanv3.php?version=1.3.32

thanks all this explained what i was doing wrong. will try to correct it now.
