[Bug 1907676] Re: segmentation fault when opening fd

[Eric Desrochers]

The current situation of python-apt is somewhat critical as no packages
can be pushed via Landscape to machines at the moment. This is causing
landscape-package-changer to segfault as follows:

[apport-retrace]
Core was generated by `/usr/bin/python3 /usr/bin/landscape-package-changer --quiet'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 ararchive_new (type=0x7f652626e0a0 <PyDebFile_Type>, args=<optimized out>, kwds=<optimized out>)
at python/arfile.cc:438


This seems to be a fix candidate:
