Upgrade wierdness

[Fiat_Lux]

Not worth filing a bug report.

Xubuntu 14.10
Python 2.7.8
Python 3.4.2

Upon upgrading to Calibre 2.12.0 from Calibre 2.8.0.

sudo -v && wget -nv -O- https://raw.githubusercontent.com/ko...x-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

That fails with an error message

2014-12-18 07:16:47 URL:https://raw.githubusercontent.com/ko...x-installer.py [25789/25789] -> "-" [1]
Installing to /opt/calibre
Downloading tarball signature securely...

The fix is to replace python with python3.

sudo -v && wget -nv -O- https://raw.githubusercontent.com/ko...x-installer.py | sudo python3 -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

Whoever maintains your distros python needs to realize that backporting only some changes from 2.7.9 to 2.7.8 is a bad idea. Either upgrade to 2.7.9 or dont. They have apparently backported the changes to the ssl module, but not the corresponding changes to the httplib module. Sigh.

I really, really wish linux distros would just stop messing with upstream packages, they simply dont have the resources for it.

Does the shell script used for Linux change, when Calibre is updated?

If it doesn't, then I'll run it as a weekly cron job, with that python3 correction.

That command is constant, it automatically fetches the most upto date version of the install script.

You might also want to see my autoupdate scripts inthe related tools subforum. Main feature -- checking if there is actually an update available. Also comes with a systemd timer.
