John,

Thank you for posting the item below.  For a progress report:

Using yumex, removing the opera repo that could not be found, and 
eliminating one conflicting package from the list of RPMs (making a 
guess as to which specific one needed to be removed, as I use the 
proprietary Nvidia Xwindows RPM and the conflict referenced nvidia, but 
not the actual kernel driver and related interfaces), I now have a SL 
7.8 system on my laptop workstation.  The issues with Firefox and 
Thunderbird seem to be resolved, and thus far, all of the applications I 
have tested, both those supplied by an EL repo as well as others (e.g., 
Nero Linux, Qoppa PDF Studio Pro, Grace, Paraview, UCSF Chimera, VMWare 
Player, VirtualBox, etc.) all seem to be working.  Thus, the system was 
left in an unstable state when I did just enough to get Kdenlive to 
run.  As it is almost midnight local time, I again have access to my 
university's IMAP and SMTP server (that in fact are for-fee Microsoft 
Exchange "cloud" services, throttled based upon the fee structure) as 
the systems at this hour of the night are not over-subscribed.

Other than for security patches, is SL 7.8 the end of SL 7?  If so, the 
next change I shall institute probably will be to Ubuntu 20 LTS that is 
due summer 2020.  I know that the home directory and related non-systems 
directories are portable from SL 7 to Ubuntu 18 LTS and thus probably to 
Ubuntu 20 LTS, as I copied all of my wife's such directories from a 
conventional laptop running SL 7 to her new Dell 2-in-1 that she needs 
to provide an on-line chalkboard (e.g., a written virtual paper tablet 
using Stylus Labs write that does work with the Dell stylus -- only the 
internal microphone cannot be made to work because Dell will not release 
in any form the microphone code that is incorporated into the Dell 
supplied Ubuntu port that was used by Canonical Ubuntu to "certify" the 
machine as Linux supported -- Dell evidently will not allow that machine 
with Dell Ubuntu to be sold in the USA market, only a MS Win version).  
Once I installed Ubuntu LTS MATE, everything worked on her machine, and 
I suspect it will work on this one as well.  Of course, I will image all 
of my personal, etc., directories onto a USB external harddrive from 
which I shall copy back to this machine once Ubuntu LTS is installed.  
At this point, I am not considering going to either CentOS or Oracle EL 8.

As we have a residential DSL Internet connection, the yumex upgrade from 
start to successful reboot lasted approximately 5 hours.  I had to wait 
until there were no Zoom sessions being required.

Stay safe.  Take care.
