I have created a github repository here:
https://github.com/eli-schwartz/calibre-installer which contains an updated calibre-upgrade.sh as well as a script à la calibre's installer, which allows for a one-liner installation of the upgrade script. (Was that statement confusing enough?
)
Run the following command in a terminal:
Code:
sudo -v && wget -nv -O- https://github.com/eli-schwartz/calibre-installer/raw/master/linux/calibre-installer.sh | sudo sh -
It will:
- Download calibre-upgrade.sh to /usr/bin/calibre-upgrade.sh
- chmod it so it is executable.
- Add the cron job to root's crontab. (If cron is not installed*, this step will fail and report that to you.)
If anyone has any improvement suggestions, I'd be delighted to hear them.
* Because on my system it isn't -- who knew? Apparently, systemd is the wave of the future, and Arch Linux wants you to use systemd timers instead of crontabs. When I get around to it (or rather, figure out how they work 
), I may write one of these timers. Meanwhile, if you are on Arch too, you can manually install a cron daemon or write your own stinking timer. 
(If anyone does, please share. </beg> )
