Ao tentar instalar o R no Ubuntu 16.04 xenial, estou preso porque r-base-core não pode ser configurado. Estou usando o manual comum . Após a instalação com falha e tentativa de configurar manualmente r-base-core , o console basicamente se parece com isto:
~$ sudo dpkg --configure r-base-core
Setting up r-base-core (3.3.2-1xenial0) ...
dpkg: error processing package r-base-core (--configure):
subprocess installed post-installation script returned error exit
status 10
Errors were encountered while processing:
r-base-core
O script de pós-instalação r-base-core.postinst
em /var/lib/dpkg/info contém o seguinte:
#!/bin/sh
#

Eu já tentei remover o script de pós-instalação para que a configuração acima seja executada sem erros e, de fato, o r-base pode ser instalado. No entanto, ao digitar R no console, é assim que o console se parece:
cannot find system Renviron

Aparentemente, o script de pós-instalação falha quando o ucf deve fazer alguma coisa. Ao adicionar o argumento -x ao script de pós-instalação:

Com base em outras postagens que encontrei on-line sobre problemas do ucf em scripts de pós-instalação, adicionei o nível de depuração 3 à linha ucf no script posinstallation. É assim que o console se parece agora:
