[Bug 1587249] Re: PIL exception fromstring
Qreator in 16.04 and beyond requires the fix to python-qrencode and this fix [1] to Qreator itself. See bug 1573577 for more details. The 16.04 Qreator package with the fix is available in the Qreator PPA. You can install it as a workaround as per the instructions on that bug. Adding them here again: sudo add-apt-repository ppa:qreator-hackers/qreator-stable sudo apt update sudo apt install qreator python-qrencode And again, if someone wants to lend a hand in doing an SRU upload to backport the Qreator fix to 16.04, help would be very welcome!

Hello Muelli, or anyone else affected, Accepted python-qrencode into yakkety-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/python- qrencode/1.01-5ubuntu1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

[Bug 1587249] Re: PIL exception fromstring
** Description changed:
+ [Impact]
+ python-qrencode is currently broken for all users in yakkety due to the
removal of Image.fromstring from pillow.
+
+ The fix is to replace all calls to Image.fromstring with
+ Image.frombytes.
+
+ [Test Case]
+ Run the following script and see if it ends in an exception:
+
+ ```
+ import qrencode
+ qrencode.encode_scaled("foo", 1)
+ ```
+
+ [Regression Potential]
+ It's unlikely that python-qrencode can regress any further, because in its
current state, both exported python methods are completely broken and will
throw an exception unconditionally with the pillow version in Yakkety.
+
+ [Other Info]
+ rdeps may also be broken if they use Image.tostring on the output. So far,
the only known rdep that is broken is qreator.
+
+ Below is the stack trace and exception thrown by the broken version of
+ qrencode.
+
In [5]: qrencode.encode_scaled("foo",1)
