Linux and arduino newbie unable to install plugin

I'm trying to install the web editor plugin and am rapidly getting in over my head. I need advice before I break something.

I'm using a 10 year old machine running knoppix 8.2.0 (4.16.5-64 GNU/Linux). The browser is chromium Version 66.0.3359.117.

Downloading the linux64 plugin and trying to install gives me the error:

/home/knoppix/ArduinoCreateAgent-1.1Arduino_Create_Bridge: error while loading shared libraries: libappindicator3.so.1: cannot
open shared object file: No such file or directory

I installed libappindicator3 files and have the following aptitude search output:

i libappindicator3-0.1-cil - CLI binding for appindicator3 using GObjec
i libappindicator3-0.1-cil-dev - CLI binding for libappindicator3 using GOb
i libappindicator3-1 - allow applications to export a menu into t
p libappindicator3-dev - allow applications to export a menu into t

Trying to install the last file gives me:

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
libappindicator3-dev : Depends: libdbusmenu-glib-dev (>= 0.1.8) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I am unable to install libbusmenu-glib-dev because of other missing dependencies. Where do I go from here to get answers?

Thanks for any help.

you did a # apt-get update && apt-get dist-upgrade
?

I did apt-get update but not dist-upgrade. Thx I'll try that

Try the 32-bit version. Old computers cannot run 64-bit programs.

Poki,

dist-upgrade just leads to another downward spiral:

udo apt-get dist-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Error!

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

oh mei ... # apt-get upgrade

der ganze Prozess wird einige Durchläufe erfordern

Fix the broken packages first. If the IDE still does not work, be sure you are using the "Linux 32 bits" version.

I am running a 64 bit version of Linux as I noted in the original post.
