python3はpython2.7.6を指します。

私が十分に注意を払っていないときに仮想環境を通過しようとしたが、Pythonのインストールを台無しにしたようです。

python3 --version
Python 2.7.6

しかし、ゴミ箱を確認してみると、状況がどうなのかよくわかりません。

ls -lah /usr/bin/python3
lrwxrwxrwx 1 root root 9 Sep 21  2015 /usr/bin/python3 -> python3.4

これが起こると、aptが正しく利用できないので、これは私を狂わせます。無効なソルバーを使用しているため、ASCIIエラーが発生します。

私はpyvenvやvenvを台無しにしたと確信していますが、何かはわかりません。助ける？

まあ、私はそれを実行し、dpkg -C半分だけコンパイルされたパッケージを得ました。主にpython3パッケージを削除して再インストールしてみました。 dpkg --configure を実行しましたが、次のエラーが発生しました。

Setting up python3-gi (3.12.0-1ubuntu1) ...
File "/usr/bin/py3compile", line 4
SyntaxError: Non-ASCII character '\xc2' in file /usr/bin/py3compile on line 4, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
dpkg: error processing package python3-gi (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 python3-gi

私の考えでは、このエラーは他のパッケージをインストールしようとしたときに表示されるため、以前も発生しましたが、スタックトレースではさらに戻ってきました。
