TH:ANK YOU! I did the following, and texis is now working!
dnf install ncurses-devel-6.1-7.20180224.el8.i686
(cd /usr/lib ;rm -f libtermcap.so ;ln -sf libtinfo.so libtermcap.so ;ln -sf libtermcap.so libtermcap.so.2)
The second command is from the workaround at
0011423: broken libtermcap.so in ncurses-devel - CentOS Bug Tracker
Again, THANK YOU!
Harold
