Official Calibre PPA?

It seems, reading the traceback, that there's something wrong in the way the linux_installer script tries to read your destination directory (/opt). Can you check its presence? I think it should be auto-created anyways, and the installer is sudoed, but well.

Also, can you check the /opt/calibre permissions and ownership?

As there have been a couple times now that Kovid pushed an updated binary due to critical errors, I upgraded my update script to allow a "force" option, this keeps everything in one script.

It looks like this now:

#!/bin/bash

# Unset git development source
export CALIBRE_DEVELOP_FROM=
# by default, switch is off
force_upgrade=0

# Functions

usage()
{
	cat <<- _EOF_
		Usage: calibre-upgrade [OPTIONS]
		Upgrades calibre installation. Automaticaly checks if the current version is up to date.

		OPTIONS
		    -f, --force        Force an update. This is only useful if binaries
		                       were updated for a critical error :shrug:
_EOF_
}

do_upgrade()
{
	cd ~/bin/calibre-portable
	rm -rf ../calibre-portable/*
	wget -O - "http://status.calibre-ebook.com/dist/linux32" | tar xjf -
}

# Options
while [ "$1" != "" ]; do
	case $1 in
		-h|--help)		usage
						exit
						;;
		-f|--force)		shift
						force_upgrade=1
						;;
		*)				echo "calibre-upgrade: unrecognized option '$1'"
						echo "Try 'calibre-upgrade --help' for more information."
						exit 1
	esac
	shift
done

# Main

	calibre-debug -c "import urllib as u; from calibre.constants import numeric_version; raise SystemExit(int(numeric_version  < (tuple(map(int, u.urlopen('http://calibre-ebook.com/downloads/latest_version').read().split('.'))))))"

UP_TO_DATE=$?


if [ "$UP_TO_DATE" = 0 ]; then
	echo "Calibre is up-to-date"

	if [ "$force_upgrade" = 1 ]; then
		echo ""
		echo "Forcing upgrade anyway -- are you sure you want to continue? [y/n]"
		read answer

		if [[ "$answer" = "y" || "$answer" = "yes" ]]; then
			do_upgrade
		else
			echo "Exiting..."
			exit 1
		fi
	fi
else
	do_upgrade
fi

Keep in mind I only use

cd ~/bin/calibre-portable
rm -rf ../calibre-portable/*
wget -O - "http://status.calibre-ebook.com/dist/linux32" | tar xjf -

to upgrade since I am not running as sudo -- I'm on a school computer ATM

There is a new install command, so make sure to update calibre-upgrade.sh everyone!

(the old version has been kept up for backwards compatibility, but we wouldn't be in this thread if we were content with plebeian methodologies. )

#!/bin/bash

calibre-debug -c "import urllib as u; from calibre.constants import numeric_version; raise SystemExit(int(numeric_version  < (tuple(map(int, u.urlopen('http://calibre-ebook.com/downloads/latest_version').read().split('.'))))))"

UP_TO_DATE=$?

if [ $UP_TO_DATE = 0 ]; then
	echo "Calibre is up-to-date"
else
	calibre --shutdown-running-calibre
	killall calibre-server

	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()"
fi

And we have more goodies, like calibre-uninstall, and an "isolated" updater.

Verily, thou speaketh the truth.

Thanks for the update!

New update! I created a sticky thread a while back describing the update script, here: https://www.mobileread.com/forums/sho...d.php?t=237233

It has now been updated with some things of mild importance (you might want to update ):

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:

sudo -v && wget -nv -O- https://github.com/eli-schwartz/calibre-installer/raw/master/calibre-installer.sh | sudo sh -

It will:

1. Download calibre-upgrade.sh to /usr/bin/calibre-upgrade.sh
2. chmod it so it is executable.
3. 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> )

• Makes sure you run as root.
• Prettier messages when calibre is not yet installed. Instead of getting a lot of "bash: ****: command not found".
