Binary linux installer fails because of bug in proxy debugging output

[Adrianna Pińska]

I run Calibre on Ubuntu, performing the manual binary upgrades as described on the Calibre homepage: http://calibre-ebook.com/download_linux

I am currently running 1.25, and when I tried to upgrade to 1.26.0 today I got this error:

XXXXXX@XXXXXX:~$ sudo -v && wget -nv -O- https://github.com/kovidgoyal/calibre/raw/master/setup/linux-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

TypeError: expected a character buffer object

In line 352, a dict is being sent to a printing function which expects strings. I'm attaching a suggested patch. Is there a reason why this debugging output is turned on by default?

If anyone else experiences the same problem before the installer is fixed: you can work around it by downloading the installer file, applying the patch, and executing the local copy of the installer:

$ wget https://github.com/kovidgoyal/calibre/raw/master/setup/linux-installer.py
$ wget https://bugs.launchpad.net/calibre/+bug/1286274/+attachment/4001048/+files/proxy_debug.patch
$ patch < proxy_debug.patch
$ cat linux-installer.py | | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

Sorry, there's a typo in the last command of the workaround -- there should only be one pipe, not two:

cat linux-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.
