Flash plugin for FireFox on Ubuntu 8.04.1

The installation doesn't work without a minor tweak after the fact:

thushara@agni:~$ sudo ln -s /usr/lib/libssl3.so.1d /usr/lib/libssl3.so
thushara@agni:~$ sudo ln -s /usr/lib/libplds4.so.0d /usr/lib/libplds4.so
thushara@agni:~$ sudo ln -s /usr/lib/libplc4.so.0d /usr/lib/libplc4.so
thushara@agni:~$ sudo ln -s /usr/lib/libnspr4.so.0d /usr/lib/libnspr4.so
thushara@agni:~$ sudo ln -s /usr/lib/libnss3.so.1d /usr/lib/libnss3.so


how did i figure this out? - just start firefox on the command-line and watch it complain:

thushara@agni:~$ firefox
LoadPlugin: failed to initialize shared library libXt.so [libXt.so: cannot open shared object file: No such file or directory]
LoadPlugin: failed to initialize shared library libXext.so [libXext.so: cannot open shared object file: No such file or directory]
LoadPlugin: failed to initialize shared library /usr/lib/adobe-flashplugin/libflashplayer.so [libnss3.so: cannot open shared object file: No such file or directory]
LoadPlugin: failed to initialize shared library /usr/lib/adobe-flashplugin/libflashplayer.so [libnss3.so: cannot open shared object file: No such file or directory]

out of these, our problem is with the libflashplayer.so, seems like a dependent module (libnss3.so) is not being found.

so now, use ld to see the dependencies for the libflashplayer.so :

thushara@agni:~$ ld /usr/lib/adobe-flashplugin/libflashplayer.so

from this, we find that certain libs are missing, or are they? let's just check if they are somewhere sneaky:

thushara@agni:~$ locate libnss3.so
/usr/lib/libnss3.so.1d
thushara@agni:~$ locate libsmime3.so
/usr/lib/libsmime3.so.1d
thushara@agni:~$ locate libssl3.so
/usr/lib/libssl3.so.1d
thushara@agni:~$ locate libplds4.so
/usr/lib/libplds4.so.0d
thushara@agni:~$ locate libplc4.so
/usr/lib/libplc4.so.0d
thushara@agni:~$ locate libnspr4.so
/usr/lib/libnspr4.so.0d

thus we can just symlink our way out of this:

thushara@agni:~$ sudo ln -s /usr/lib/libssl3.so.1d /usr/lib/libssl3.so
thushara@agni:~$ sudo ln -s /usr/lib/libplds4.so.0d /usr/lib/libplds4.so
thushara@agni:~$ sudo ln -s /usr/lib/libplc4.so.0d /usr/lib/libplc4.so
thushara@agni:~$ sudo ln -s /usr/lib/libnspr4.so.0d /usr/lib/libnspr4.so
thushara@agni:~$ sudo ln -s /usr/lib/libnss3.so.1d /usr/lib/libnss3.so
