问题 I want to use ibm_db_django to connect to a DB2-database. The database runs on a Windows 7 x64 system. I also installed ibm_db and ibm_db_django on the same system. I developed my app on this computer and everything works fine. Now I wanted to deploy the django-project to a debian 6 x64 system. After some trial I installed the IBM Data Server Client (version 9.5, Fix Pack 10) and added the ODBC-driver for 32-bit. After this I was able to install ibm_db and ibm_db_django . Now I am able to

问题 I have Python 3.2 installed by default on my Raspbian Linux, but I want Python 3.4 ( time.perf_counter , yield from , etc.). Installing Python 3.4 via apt-get is no problem, but when i type python3 in my shell I still get Python 3.2 (since /usr/bin/python3 still links to it).

问题 Building our own deb packages we've run into the issue of having to patch manually some scripts so they get the proper prefix. In particular, We're building mono We're using official tarballs. The scripts that end up with wrong prefix are: mcs, xbuild, nunit-console4, etc An example of a wrong script: #!/bin/sh exec /root/7digital-mono/mono/bin/mono \ --debug $MONO_OPTIONS \ /root/7digital-mono/mono/lib/mono/2.0/nunit-console.exe "$@" What should be the correct end result: #!/bin/sh exec /usr
