Can't install Draftsight on Ubuntu 18.04

[bsnider]

Hi I have been trying to install the latest version of Draftsight (Download for Ubuntu) on my new setup with Ubuntu 18.04. I got the following error messages in Terminal when trying the following:

bruce@bruce:~/Downloads$ sudo dpkg -i draftSight.deb
(Reading database ... 174397 files and directories currently installed.)
Preparing to unpack draftSight.deb ...
access control disabled, clients can connect from any host
/var/lib/dpkg/tmp.ci/ShowLicense: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
access control enabled, only authorized clients can connect
dpkg: error processing archive draftSight.deb (--install):
new draftsight package pre-installation script subprocess returned error exit status 127
Errors were encountered while processing:
draftSight.deb

I would appreciate any suggestions you might provide about this !!! Thanks !!!

I'd try
sudo apt install ~/Downloads/draftSight.deb apt will try to download and install dependencies of a package before the package itself, dpkg doesn't do that.
If that doesn't work, please post whatever messages it shows.

Check whether the library libgtk-x11-2.0.so.0 is actually available on your system ('locate libgtk-x11-2.0.so.0'). On my system it is (three times,actually; 32 bit version, 64 bit version and once as part of a snap ...) and was installed as part of the package 'libgtk2.0-0'. If it doesn't exist you could install that package using 'sudo apt install libgtk2.0-0'. If it does exist and the installation script of Draftsight doesn't recognize or find it, then I'm out of ideas for the moment ...

Thank you Holger. As you suggested, I ran 'locate libgtk-x11-2.0.so.0' and found that I had that located in several spots, many of them were for this GIMP program I have installed.

I'm not sure why, but this time I ran "sudo apt install ~/Downloads/draftSight.deb" again and this time the installation worked!!

Since earlier, I installed the program called Freecad, and this installed some different background software, maybe that helped.
