[Touch-packages] [Bug 1540168] Re: Update OpenCV version for 16.04
I have just started using xenial to prep our own software for the release. I was shocked that CV 3.0 is not installed. Surely this should be an exception to the feature freeze as already suggested, having to keep installing from source would be a huge pain. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to opencv in Ubuntu. https://bugs.launchpad.net/bugs/1540168 Title: Update OpenCV version for 16.04 Status in opencv package in Ubuntu: Confirmed Status in opencv package in Debian: Fix Released Bug description: The Ubuntu 16.04 alpha still only contains OpenCV 2.4.

[Touch-packages] [Bug 1556156] Re: OpenCV lacks Python 3 bindings
Not good state of affairs for the new LTS. 3.0 needs to be part of the release, I also think an exception should be made. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to opencv in Ubuntu. https://bugs.launchpad.net/bugs/1556156 Title: OpenCV lacks Python 3 bindings Status in opencv package in Ubuntu: Confirmed Status in opencv package in Debian: New Bug description: Because the packaged OpenCV remains at the obsolete 2.4 release even still in 16.04 (Xenial Xerus), which is already in feature freeze, it is looking as though 2018 is the earliest that an Ubuntu LTS release will package OpenCV 3.x, which at that point will be already some 4 years old. (And the currently-shipped OpenCV 2.x branch will be going on 9 years.) See bugs #1516985 and #1540168. This is not a great state of affairs for such an important package, but what exacerbates the situation is that OpenCV in Ubuntu (and in Debian) currently altogether lacks Python 3 support. Namely, the current OpenCV 2.4 packages support only Python 2.7, since Python 3 support was introduced only in OpenCV 3.0 [1], which was only packaged in Debian (experimental) last December. This has already been a pain point for OpenCV users (and some packages requiring OpenCV) and is likely to become a burning problem over the course of this LTS release's lifecycle. The robotics community (e.g. ROS users), in particular, rely on Ubuntu LTS as a platform, and are going to be rather rudely surprised both by Xenial's old OpenCV release and still more by its lack of Python 3 support. The relevant upstream Debian bugs are 799262 [2] and 792677 [3]. As mentioned, OpenCV 3.0 has already been packaged in Debian (packages libopencv-*3.0) and could be imported to Ubuntu. The Python bindings (python-opencv) still remain with a Python 2.7 requirement, however, which needs work upstream. What can be done here? Would there be any prospect at all for a feature freeze exception so as to ship OpenCV 3 for Xenial? Once the base libraries are available, the Python 3 packaging is a much lesser problem and could even be done via PyPI.

100% agree. This is a disaster for Ubuntu. OpenCV is hugely important to a ton of people. On Fri, Apr 8, 2016 at 4:29 PM, combieone wrote: > Wow, this is outrageous, it needs to be fixed immediately.
