"error while loading shared libraries: libicui18n.so.63"
Solution 1:
I had a similar problem trying to use Visit software.
I solved the problem using the advise of this tweet: https://twitter.com/sinclairinat0r/status/1237201767198273536
wget http://mirrors.edge.kernel.org/ubuntu/pool/main/i/icu/libicu63_63.2-2_amd64.deb
sudo dpkg -i libicu63_63.2-2_amd64.deb
For me it solved the dependency missing.
