This is definitely tangential to the list: I'm on Ubuntu (22.04.2 LTS)
not Debian and I'm sure this is about issues in the Ubuntu package
management
on my machine, R is only revealing them.
The original subject line came from me wondering if my going over to the r2u
repository would solve the problem. However, as I think Dirk said, that's
only really likely to be answered by trying it and I would rather see if I
can understand what has gone wrong before I do anything radical.
I am also hoping that having this, partially OTT thread on the list may
help as I doubt if I'll be the last to hit this sort of package management
nightmare. Some of the issues clearly are pure OS issues but the impact
for me is definitely on R.

Hi Chris,
Thanks for posting here, and sorry I missed it for two days due to sorting
mailing list traffic into folders and clearly not glancing at all of them.
Don't think I said before how much I appreciate you responding at all.

That can happen, and pinning can help. I would suggest to look at 'apt-cache
polict nameofthepackagehere'. (See below for concrete example.)
So I try this.
root@Clevo2:/media/chris/Clevo_SSD2/Data/MyR/R/distill_blog/test2/_posts#
apt-cache policy libmagick++-dev
libmagick++-dev:
Installed: (none)
Candidate: 8:6.9.11.60+dfsg-1.3ubuntu0.22.04.3+esm2
Version table:

Packages
500 http://mirror.infomaniak.ch/ubuntu jammy/universe i386 Packages
And the key problems remains this (actually, it's got a bit worse):
root@Clevo2:/media/chris/Clevo_SSD2/Data/MyR/R/distill_blog/test2/_posts#
apt-get install libmagick++-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
libcairo2-dev : Depends: libfontconfig1-dev (>= 2.2.95)
Depends: libfreetype6-dev (>= 2.1.10)
libglib2.0-dev : Depends: libglib2.0-0 (= 2.72.4-0ubuntu1) but
2.72.4-0ubuntu2.2 is to be installed
Depends: libglib2.0-bin (= 2.72.4-0ubuntu1)
Depends: libglib2.0-dev-bin (= 2.72.4-0ubuntu1)
libmagickcore-6.q16-dev : Depends: libfreetype6-dev
libwmf-dev : Depends: libfreetype-dev but it is not installable
E: Unable to correct problems, you have held broken packages.
Which brings me to Dirk's on the nail question:
(Also: how come there are two libmagick++-dev, ie why do you have a 2nd one,
ie do you know which additional repo you turned on?)
Exactly!!! The weird thing is is that it was weeks back that I added a
repo., or
I think I did, probably more than one about handling gpx files in
Ubuntu/Debian.
But that was weeks before this started and as you see from that
apt-cache policy
(if I understand it correctly), the repos involved seem to be the
mainstream ones.
That's true when I do apt-cache policy on any of the packages that are
being
complained about.
aptitude doesn't help and dpkg --get-selections | grep hold returns
nothing (literally)
and none of the other things I could find on the web about these sorts
of collisions
helped ... and I can't see that others have this problem (apart from
some very old
reports for Ubuntu 14 and 16!)
Are there any more suggestions? Are there good Debian/Ubuntu places
where I should
be putting this? If so, any advice about how to word it?!
Are there frightening radical steps I should take next?!
... and back to the human
Cheers, Dirk
Cheers indeed.

Nice. I got to workshop-keynote once in Guayaquil and regret not making over
to Quito.
Ah, I'm the reverse. Ecuador seems to be sliding into a frightening
narcogang
dominated state that previously it had always avoided. I guess that puts my
problems in perspective.
