Hi,
I just stumbled across this issue when trying to recompile the uswsusp
package with pbuilder & pbuilder-satisfydepends-gdebi.
It happens when the package's control file contains non-ASCII
characters. In uswsusp's case, the Maintainer field contains "Rodolfo
García Peñas (kix) <[email protected]>".
It seems /usr/lib/python3/dist-packages/apt/debfile.py does not account
for this and I'm not sure how this could be fixed (does the Debian
policy even state what the character encoding should be for the control
file?)
To see which field triggers the error, I patched the open method inside
the DscSrcPackage class and replaced line 745:
self._sections[tag] = sec[tag]
with:
try:
self._sections[tag] = sec[tag]
except UnicodeDecodeError as e:
raise ValueError(tag)
I also replaced the call to logger.debug in the code fragment quoted by
Mattia Rizzolo with a call to logger.error (so that the error actually
gets display on the console when running pbuilder)
Now, I get this kind of output:
I: Installing the build-deps
ERROR:root:error opening: Maintainer
Failed to open the software package
The package might be corrupted or you are not allowed to open the file. Check
the permissions of the file.
Which put me on the right track. And sure enough, if I remove the
diacritics from kix's fullname, I can now rebuild the package just fine.
Regards,
François
