dpkg retorna erro, não pode instalar pacotes

Question

Estou com problemas para instalar pacotes. O dpkg sai com erros:

sudo dpkg -i /var/cache/apt/archives/libglapi-mesa-lts-trusty_10.1.3-0ubuntu0.2~precise2_amd64.deb
(Reading database ... 945234 files and directories currently installed.)
Unpacking libglapi-mesa-lts-trusty (from .../libglapi-mesa-lts-trusty_10.1.3-0ubuntu0.2~precise2_amd64.deb) ...
xz: /usr/lib/x86_64-linux-gnu/liblzma.so.5: version 'XZ_5.2' not found (required by xz)
dpkg-deb (subprocess): subprocess data returned error exit status 1
dpkg-deb: error: subprocess <decompress> returned error exit status 2
dpkg: error processing /var/cache/apt/archives/libglapi-mesa-lts-trusty_10.1.3-0ubuntu0.2~precise2_amd64.deb (--install):

Errors were encountered while processing:
 /var/cache/apt/archives/libglapi-mesa-lts-trusty_10.1.3-0ubuntu0.2~precise2_amd64.deb

A execução de dpkg -a --configure foi recomendada, mas não corrigida. Algum conselho?

Edit: libzlzma está lá:

$ sudo find / -name liblzma.so.5
/usr/local/lib/liblzma.so.5
/usr/lib/x86_64-linux-gnu/liblzma.so.5
/home/anaconda2/lib/liblzma.so.5
/home/anaconda2/pkgs/xz-5.2.2-0/lib/liblzma.so.5
/home/.conda/envs/outrigger-env/lib/liblzma.so.5
/home/xz-5.2.3/src/liblzma/.libs/liblzma.so.5

Descobri:

Anaconda2 era uma cópia conflitante:

n$ which xz
/usr/local/bin/xz

$ xz --version
-bash: /home/acct/anaconda2/bin/xz: No such file or directory
$ echo $PATH
/home/acct/anaconda2/bin:/home/acct/perl5/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Ran:

$ export PATH='echo ${PATH} | awk -v RS=: -v ORS=: '/anaconda2/ {next} {print}''
$ xz --version
xz (XZ Utils) 5.2.3
liblzma 5.2.3

E agora os pacotes são instalados corretamente. Estranho embora b / c eu instalei o anaconda meses atrás e o erro acabou de chutar ontem.
