How do I update Calibre in Ubuntu?

[baron164]

I setup Calibre Server to run on an Ubuntu 16x server. I installed Calibre using this command:

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()"

My question is, since I did not use the apt-get process of installing Calibre, how do I go about updating Calibre when new versions come out? I'm assuming I do not simply re-run the same command and I'm hoping someone can point me in the right direction.

I'm actually thinking that you do. The .py file would be updated from git, someone correct me if I'm wrong.

You simply re-run the same command.

Ok, thank you. I wasn't sure and didn't want to risk overwriting everything I had already done.

Installation/un-installation touches only program files, never data files.

I ran the same wget command again and it appeared to update but I ran into a couple of issues.

The first issue was that it removed the calibre.log file from /opt/calibre so I had to recreate it and then assign it permissions.

The second issue and the one I haven't been able to fix is now when I try to access the site I get this message.

Failed to load books from calibre library, with error:
Failed to communicate with "/interface-data/books-init?library_id=calibre-library&sort=timestamp.desc&1528739880411", with status: [500] Internal Server Error

Not sure what went wrong.

*Update

I restored my backup and then check the /opt/calibre directory before the update and and after and saw that both the calibre.log and server-users.sqlite files were missing after the update. I ran the update again and this time after it finished I copied the log and sqlite files back over and this time the site appears to be working properly.

I moved the calibre.log and server-users.sqlite files out of the /opt/calibre directory so that next time I run the command I won't need to worry about these two files. Should also make automating the update much easier.

Why are you creating calibre.log and the sqlite file in the installation directory? The only way that can happen is if you have set the CALIBRE_CONFIG_DIRECTORY environment variable to the installation directory. Dont do that.

[baron164]

The guide I was following for the install had me create them in the directory. As this is my first time with the Linux version of Calibre I just didn't know any better. But now I do and I certainly won't do that again :-)

Ah, well in that case, welcome to Linux
