Bug #14326
Updated by Javier Bértoli about 6 years ago
When installing @python3-certbot@ from @stretch-backports@, which depends in @python3-future@ along with @python-arvados-python-client@, apt fails with <pre> dpkg: error processing archive /var/cache/apt/archives/python3-future_0.16.0-2_all.deb (--unpack): trying to overwrite '/usr/bin/futurize', which is also in package python-future 0.16.0-2 </pre> The issue is that * python-arvados-python-client depends on @python-future@ @python-futurize@ * python3-certbot depends on @python3-future@ @python3-futurize@ * Our packages @python-future@ @python-futurize@ and @python3-future@ @python3-futurize@ have precedence over the distro ones, due to @apt-preferences@ * Our packages have invalid content and do not differentiate between versions. While the distro's packages have: * @python-future@ @python-futurize@ contents: <pre> ... ./usr/bin/python2-futurize ./usr/bin/python2-pasteurize ... ./usr/lib/python2.7/dist-packages/ ... </pre> * @python3-future@ @python3-futurize@ contents: <pre> ... ./usr/bin/python3-futurize ./usr/bin/python3-pasteurize ... ./usr/lib/python3/dist-packages ... </pre> The Arvados' repo packages have * @python-future@ @python-futurize@ contents: <pre> ... ./usr/bin/futurize ./usr/bin/pasteurize ... ./usr/lib/python2.7/dist-packages </pre> * @python3-future@ @python3-futurize@ contents: <pre> ... ./usr/bin/futurize ./usr/bin/pasteurize ... ./usr/lib/python3.5/dist-packages ... </pre>
