Well I have been meaning to write a piece about upgrading but ... what exactly
is
your issue here, and how can we help?
For context, I _never_ reinstall R packages when R upgrades (apart, of
course, for changes like R 4.0.0 when we had to). So in my standard place,
ie /usr/local/lib/R/site-library, a month after R 4.5.0 came, it is still a
healthy mix of packages installed with R 4.5.0, 4.4.*, 4.3.* and possibly
older. They all work.
Now, back to your question: I am not aware of a repo for Ubuntu that mimicks
snapshot.debian.org giving you all builds. But if you look at
packages.ubuntu.com and search you get this
https://packages.ubuntu.com/search?keywords=r-base&searchon=names&suite=all§ion=all
indicating 4.4.1 in 24.10 and 4.4.3 in 25.04. Your 24.04 only has 4.3.3. But
read on...
But if you really think you must use R 4.4.* on Ubuntu 24.04 you can always
compile it locally, as package (ie build a .deb if you know how) or into
/usr/local. But read on...
All that said, I think it is a non-issue. R 4.5.0 works great on 24.04 and
later _and that is why we offer the backport via CRAN_.

To prevent apt and dpkg from upgrading a package, you can place a
'hold'. See
the dpkg documentation (man dpkg) and look for hold. You pass the package
name and the state ("hold") 'piped' to dpkg --set-selection,
if I remember
correctly. There are likely some tutorials somewhere.
Now, given a particular set of apt repos (that is your local admin choice
after all) you can always call 'apt-cache policy r-base-core' to see
what is
know. You will likely see r-base-core 4.4.3 still listed. You *can* in fact
instal that from that CRAN mirror repo by giving an explicit version argument
so
sudo apt install r-base-core=4.4.3-1.2404.0
should work but you likely need to add additional packages there to satisfy
apt ie
sudo apt install r-base-core=4.4.3-1.2404.0 r-base-dev=4.4.3-1.2404.0
and so on.
After this you must use the 'dpkg hold' trick to not update 4.5.0 over
4.4.3
again.
