As Promethean doesn't care about its users (at least Ubuntu users), here's my help:
Installing ActivInspire and ActivBoard and all that stuff:
1. Install Kernel headers:
$ sudo apt-get install linux-headers-$(uname -r)
2. Install the key and repository:
$ cd /tmp
$ wget http://activsoftware.co.uk/linux/repos/Promethean.asc -O key
$ sudo apt-key add key
$ echo deb http://activsoftware.co.uk/linux/repos/ubuntu precise oss non-oss | sudo tee /etc/apt/sources.list.d/promethean.list
3. Install ActivInspire in UK English (or your own language):
$ sudo apt-get update
$ sudo apt-get install activ-meta-en-gb
4. Deceive ActivInspire with some library versions:
$ sudo ln -s /usr/lib/i386-linux-gnu/libjpeg.so.8 /usr/local/lib32/libjpeg.so.62
For 64bit Ubuntu versions:
$ sudo ln -s /lib/x86_64-linux-gnu/libudev.so.1 /usr/local/lib/libudev.so.0
For 32bit Ubuntu versions:
$ sudo ln -s /lib/i386-linux-gnu/libudev.so.1 /usr/local/lib/libudev.so.0
Last but one. You can (but maybe there's no absolute need to) install libicu:i386 in the 64bit versions of Ubuntu 14.04:
$ sudo apt-get install libicu-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/libicui18n.so.52 /usr/local/lib32/libicui18n.so.42
Last. If anything goes wrong, try to run
$ activmgr
and/or
$ inspire
from the terminal, to look at the errors.
