Potential Issues Upgrading? from 3.21 :O

rebeltaz · 03-10-2022, 10:32 PM

I run Ubuntu 18.04 LTS and I installed calibre from the repository. When things work, I'm the kind of person who doesn't necessarily "upgrade" just for the sake of upgrading. Apparently the version in the repository is 3.21

while the latest version is 5.38! Wow...

So, my question(s) is(are) is there any real reason to "upgrade"? And 2) if I do decide to "upgrade" would there be any potential issues of which I should be aware "upgrading" from such an older version to the latest?

Thanks!

The structures in your library are in calibre version 3.
No problem upgrading from 3 to 5.
Just copy the installer from the official Calibre page in your terminal and you will have the latest version without problems

I appreciate that. After talking to some people on reddit, I think I'm just going to stick with 3 right now. It's working so no real reason to risk breaking it

Thank you, though!

If you do not need a newer device driver or newer feature, why not stay

At some time, you will need to update. Best if the reason and need do not happen at the same time. (ie a new device or OS)

But do not update from the repository. It can be a nightmare. Upgrade from the Calibre website.

But one could try Calibre 4.23 and if that works, then move to version 5. That way if version 5 is not working, one can go back to 4.23 which is compatible with the version 5 database. It's a win-win.

The only thing to do is backup the configuration directory before upgrading.

Yeah... not a problem here. 3.21 is the "latest" in the Ubuntu 18.04 repository, so if I ever do decide to update calibre, the official website would be my ONLY option. Thanks!

A lot of people have problems with the repository verion of Calibre. Also, 3.23 is the last version 3.

So yes, your repository is meh at best. It should have 5,28.

Honestly, my only grip with 3.21 is that there's no "read" checkbox for titles, but... that is a small inconvenience as worst. Otherwise, it's been working great for me.

There isn't a "read" checkbox in any version of calibre. Or at least there isn't if what you mean is to mark a book as read. (I can't think of another meaning). How to record that books have been read has been discussed here many times with lots of different solutions. The simplest is to add a "Yes/No" custom column and change that when the book is read. The other ways depends on what info you want store about the books that have been read.

That was exactly what I did

I plan to upgrade from Calibre 3.48 to 5.38 soon. I'm doing some testing now to make sure no surprises will pop up for me.

Does anyone here use "Calibre-Web" as their web presence for Calibre? Is it compatible with the new format of the Calibre database (this new format is something I just learned about while reading this thread) ...

Note that "Calibre-Web" is NOT the built-in Calibre web server. This is a third party software that reads the Calibre database. I use Calibre-Web because I like the interface it provides better than the native Calibre server. My choice here may change when I do more testing of Calibre 5.38. Could be that this newer version of Calibre has a web interface that is better suited to my needs than the old one in 3.48. But for now, I'm planning on continuing to use Calibre-Web. I will do my own testing, but if there are known incompatibilities it would be good to know that up front.

I've noissues with calibre-web and current calibre versions. I replicate my local calibre library to a raspberry pi with calibre-web on it.
