Eu tive um problema semelhante com o qt, então fiz isso e funcionou: https://askubuntu.com/a/1274166/806813
Mas para este, eu só consegui encontrar: http://neuro.debian.net/install_pkg.html?p=libvtk5-qt4-dev
Eu recebo um erro na atualização:

para o qual agora o erro é:
Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'python-dev-is-python2' instead of 'python-dev' Note, selecting 'pylint' instead of 'pylint3' E: Unable to locate package libvtk5-qt4-dev
Este é um erro GPG. Este erro ocorre quando você tenta instalar um pacote de uma fonte desconhecida. Ao receber este erro, você não poderá atualizar seu repositório. Para corrigir este erro, você deve importar a chave GPG pública.
O problema é mencionado na descrição do erro:
"As seguintes assinaturas não puderam ser verificadas porque a chave pública não está disponível: NO_PUBKEY A5D32F012649A5A9 "
