if [ $(lsb_release -r | awk '{print $2}') == '18.04' ]; then

In my situation(Ubuntu 20.04),there was another error about ftp connection problem.The log is something like below:

Connecting to ftp2.adobe.com (ftp2.adobe.com)193.104.215.67:21...connected.
Logging in as anonymous ..
Error in server response,closing control connection.
Retrying.

I use the direct downloading link which is alternative of the commadn wget ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/AdbeRdr9.5.5-1_i386linux_enu.deb in the script to solve the problem:wget http://ardownload.adobe.com/pub/adobe/reader/unix/9.x/9.5.1/enu/AdbeRdr9.5.1-1_i386linux_enu.deb
