Forum - Another libcurl3 version problem

Hi,

I skipped the problem with libcurl4-openssl-dev a few days ago by ignoring it. But now I'm running into the same problem again -- seems libcurl3 is quite commonly used...

So this time I'm trying to install mopidy, in order to stream spotify (following instructions here: https://docs.mopidy.com/en/latest/installation/debian/#debian-install).

The error I get (see below) is about libcurl3-gnutls, and I got the wrong version installed (need 7.38.0 but have 7.37.1-1).

Is this something I can get fixed / changed?

Terminal

xbian@xbian ~ $ sudo apt-get install mopidy

I don't know the reason for using an older libcurl3-gnutls, but you can try to comment out the part in /etc/apt/preferences.d/xbian and try again

Ah, thanks for that. I didn't realise that's where the version was 'fixed'.

Ok, I've taken it out, updated, and everything still seems to work. I'll let you know if anything breaks.

Just to update:

This fix worked fine for a while, but preferences.d was replaced with the original version at some point. apt-get upgrade then downgraded libcurl3 and removed the software I had installed (it might have asked me for permission, I can't remember seeing it though). So.. you mileage with this fix will, like Volkswagen emissions, vary depending on whether you're in a test situation or not.

It would be really good to know why libcurl3 is 'pinned' in this way and whether there are plans to change that.

A file /etc/apt/preferences.d/01user with

Code:

Package: libcurl3 curl libcurl3-gnutls

Pin: release o=Debian

Pin-Priority: 1001

Package: libcurl3 curl libcurl3-gnutls

Pin: release o=XBian

Pin-Priority: -1

will make debian's version a priority again

Edit:
Wrong order in example file, fixed version see below

Ah, thanks for that! Will give that a whirl.

Is there a manual to understand what works how here?

The file 01user posted above is not correct. It should be:

Code:

Package: libcurl3 curl libcurl3-gnutls

Pin: release o=XBian

Pin-Priority: -1

Package: libcurl3 curl libcurl3-gnutls

Pin: release o=Debian

Pin-Priority: 1001

And it works, checked by myself Smile
