I thought all package managers handle uninstalling...

There is an official Arch guideline that users should make the choice to activate things or not, but I decided if one is installing my updater, one wants to use it.
Arch guidelines also say calibre should ship with bunded and modified libs stripped out a la debian.
Besides, I echoed a message -- good enough.

I haven't seen my sandbox "packaging" after installing, might'Ve just flown by, seeing as I normally have it confirming outright when I check contents beforehand.

I can't say if it comes like that, haven'T used pacman for installing, stuck to your installer (What works, works, and considering calibre updates faster then manjaro does it's packages, they hang behind two or three releases at best).

Not sure what you mean, but AUR helpers use makepkg and install the resulting package, and usually clean up the *.pkg.tar.xz afterward.

Interesting, Arch itself doesn't lag but it appears unlike other Arch derivatives Manjaro doesn't use archlinux.org repos. (Others will add custom overriding repos, e.g. parabola has a blocklist and all their libre stuff but finally pulls packages directly from Arch.)


Anyway good to hear it works.

Manjaro claims to be binary compatible. Doesn't mean they're using the same repos... I need to look up the part of their history explaining that... -EDIT- Found it :LINK: - And another

It does, taking aside that one gremlin from the major version move. And it does what it is supposed to with a zeal that is missing from a lot of software nowadays.

I am thinking of implementing your script on my Linux Mint 18 home server. I have setup calibre-server to run at startup with a systemd script:

Code:
[Unit]
Description=Calibre as a system service with webserver
After=network.target
AssertPathExists=/home/matt/mounts/ServerFolders/Books

[Service]
Type=forking
PIDFile=/var/run/calibre-server.pid
ExecStart=/usr/bin/calibre-server \
        --daemonize \
        --max-cover=1200x900 \
        --max-opds-items=30 \
        --max-opds-ungrouped-items=100 \
        --url-prefix /cops \
        --username=user \
        --password=password \
        --port=8080 \
        --pidfile=/var/run/calibre-server.pid \
        --with-library='/home/matt/mounts/ServerFolders/Books/Calibre Library Oden/'

[Install]
WantedBy=multi-user.target
Which runs at startup and is controlled with:
Code:
sudo systemctl [start|stop|restart|status] calibre@matt.service
Will your script work ok with this setup, ie will it be able to stop and start the server after it runs?

Well, it will kill the server, yes. `killall` as root is good at that.
And your calibre@matt.service does not specify restarting on failure (or any kind of restarting at all), so it won't restart before the upgrade completes, in fact, you will have to restart it yourself.

Note that the only real reason to kill all calibre processes during an upgrade is to restart them with the new version of calibre, since Linux is perfectly capable of replacing the program files while it is still running.

...

I would try using the "Conflicts=" directive in your calibre-server service, to get it to stop when the upgrade service is running. (I haven't thought about this situation before. I haven't tested it and I am not sure how to make sure it restarts as well. I don't know whether the "Restart=always" directive would restart it when the Conflicting service ends.)

..

Aside: I use the following systemd template service to start the server.

Code:
[eschwartz@arch ~/git/calibre-installer]$  cat ~/.config/systemd/user/calibre-server@.service
[Unit]
Description=Main calibre server
After=network.target

[Service]
EnvironmentFile=/%h/.config/calibre/servers/%i.conf
ExecStart=/usr/bin/calibre-server \
    --port="${port}" \
    --with-library "${path}" \
    --restriction "${restriction}" \
    --user "${user}" \
    --pass "${pass}"

[Install]
WantedBy=default.target
It is run as a user service.

Note that calibre-server does not need to be `--daemonize`d. pidfile+daemonize was necessary for earlier init systems which unlike systemd didn't natively know how to track the lifetime of the executable.

Also note my use of EnvironmentFile to easily template different servers.

In ~/.config/calibre/servers/${server}.conf you can drop values for:

Code:
port=""
path=""
restriction=""
user=""
pass=""

Is this script still alive and working on a Raspberry Pi, too?

Well, sure the script still works. But all it does is install the official prebuilt binaries. And there have never been prebuilt binaries for the raspberry pi.

I suggest you use https://archlinuxarm.org instead, as they provide an up-to-date ARM build of calibre that should work okay.

Well, at least Arch Linux makes it trivially easy to build your own if you would prefer something a little more recent than 3.0.0 (we're four minor versions ahead now), but even so that is much more recent than e.g. raspbian.

The script at https://github.com/eli-schwartz/calibre-installer relies on this page to do the update check:
http://code.calibre-ebook.com/latest

But for the last week or so that page or site was sometimes down (404 error) and it still has an invalid certificate which causes exceptions. I've written a slightly altered script which uses Github's REST API to check the version, since github.com is less likely to go down than the above

Code:
## Downloads and installs the latest version of Calibre from the Calibre website if not already installed
    # From https://www.mobileread.com/forums/sh...93#post2691093 and https://github.com/eli-schwartz/calibre-installer and modifications by me to support the fact that the original site that had the latest Calibre version info is now offline as of July 2017
    LATESTCALIBREVERS=`curl --silent --max-time 10 https://api.github.com/repos/kovidgo...eleases/latest | jq --raw-output '.tag_name' | cut -c2-6 -`
    calibre-debug -c "from calibre.constants import numeric_version; raise SystemExit(int(numeric_version  < (tuple(map(int, '$LATESTCALIBREVERS'.split('.'))))))"
    UP_TO_DATE=$?

    if [ $UP_TO_DATE = 0 ]; then
            echo "Calibre is up-to-date"
    else
            killall --quiet calibre-server
            ORIGUMASK=`umask`
            umask 0022 # Calibre installer needs umask 0022
            python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('https://raw.githubusercontent.com/kovidgoyal/calibre/master/setup/linux-installer.py').read()); main(install_dir='/opt')"
            umask $ORIGUMASK # restore original umask value
    fi

As I mentioned on Github, I don't see those 404's (and I don't see how an HTTP domain that doesn't redirect to https:// can possibly result in an SSL certificate error), but regardless I've decided to use calibre's internal update notifier logic for that check anyway for separate reasons. It's a bit cleaner in terms of nested logic, and it is also future-proof as long as calibre maintains the same API which seems reasonable.
Note that calibre's internal update notifier logic embeds the private SSL certificate for that subdomain.

Code:
from calibre.gui2.update import get_newest_version
get_newest_version() # returns a tuple of the version from http://code.calibre-ebook.com/latest
...

On a side note. I've started gpg-signing my commits and tags, as well as the release archive (deterministically regenerated locally). So in case you wanted to check the PGP signature of this script -- which, since it just uses linux-installer.py, downloads and installs calibre without checking the PGP signature of calibre that is in fact available for checking -- you can now do that.

Regarding which, my PGP key fingerprint is:
Code:
BD27 B07A 5EF4 5C2A DAF7  0E04 8481 8A68 19AF 4A9B

While I agree that going with Arch for a Calibre-only server, just for those guys who are looking for a Raspbian workaround: https://www.raspberrypi.org/forums/v...9037&p=1086130

This is essentially changing the source list to "testing" and thus installing an newer (but potentially less stable) version than the 2.75 coming with Jessie. 3.4.0 seems in testing now.

Based on eschwartz recommendation, I actually installed Arch Linux on my Raspberry Pi now, ran the script but ended up with:

[root@syncpi bin]# calibre-upgrade.sh
Calibre is not installed, installing...

raise child_exception_type(errno_num, err_msg)

I don't know much about Linux but it looks like it tries to install a i686 and not arm version.

I'm a bit confused now: how to install Calibre on a RPI w/ arch linux?

If I interpret the discussion here correctly, I CANNOT use the script but should install the "normal" AUR package (not the installer AUR package)?

---

EDIT / follow up:

When I try to install the AUR package I get:

[alarm@syncpi calibre-git]$ makepkg -si
==> ERROR: calibre-git is not available for the 'armv7h' architecture.

==> ERROR: An unknown error has occurred. Exiting...

Now what?

You have two options:
  1. Install calibre from the official Arch Linux ARM repositories, via
    Code:
    pacman -S calibre
  2. Install calibre-git from the AUR, since you are on a PI which is not standard i686/x86_64 desktop arches but rather armv7h you will usually have to run
    Code:
    makepkg -si --ignorearch
    As I do not test the armv7h build myself, I am unwilling to commit to adding that as a supported arch in the PKGBUILD, but using --ignorearch is pretty common for PI users to install AUR packages that probably compile okay on ARM architectures.
