mv: не может переместить ‘jdk1.8.0_91’ в ‘java-8-oracle/jdk1.8.0_91’: Каталог, не пустой

Я пытаюсь установить Heroku локально в мой LTS Ubuntu 14.04.

Но я получаю эту ошибку:

The following NEW packages will be installed:
 heroku
0 upgraded, 1 newly installed, 0 to remove and 198 not upgraded.
1 not fully installed or removed.

Кто-либо встретился с этой проблемой? И как зафиксировать его? В настоящий момент я думал для изменения владельца и группы для этих двух каталогов, но я не знаю последствий.

Спасибо за любые предложения!

Я забыл упоминать структуру этих двух каталогов:

6952928 drwxr-xr-x  9 uucp  143      4096 iul 22 19:41 java-8-oracle
6832129 drwxr-xr-x  8 uucp  143      4096 apr  1  2016 jdk1.8.0_91

который выглядит странным для меня. Особенно это uucp 143. При необходимости во мне для обеспечения большего количества информации, спросите, поскольку я не так совершенствуюсь в Linux (или такой).

Снова, Спасибо!

LE2:

После следования за идеей @Zanna я переименовал те два каталога, и я запустил установщик снова. Unsuccessfull, поскольку я получаю следующую ошибку:

heroku is already the newest version.

Да, я использую ppa. Я попробовал эти шаги для чистки пакета: Я установил ppa-чистку, затем я выполнил вторую команду для удаления ее. Я получил эту ошибку:

# First I installed ppa-purge, and at the end, I got the same error: E: Sub-process /usr/bin/dpkg returned an error code (1)

# Here I tried to purge the package

sudo ppa-purge ppa:webupd8team/java
Updating packages lists
PPA to be removed: webupd8team java
Warning:  Could not find package list for PPA: webupd8team java

И теперь я не могу понять, почему это предупреждение, поскольку оба каталога существуют. Additionaly, я получил это ошибочное окно также.
