@catb0t did you mean that pure-complete errors, but pure-base works? If that's so, can you please try pure-math and post the install log here? I'm trying to figure out what exactly goes wrong there, as I can't reproduce this issue. Maybe there's a dependency gone missing somewhere, which happens to already be installed on my system.
from pure-lang.
I'm afraid that I can't reproduce this. No matter what I try, the entire collection always installs fine for me. That's on a fully updated Bionic system with the apt cache cleared beforehand.
Does pure-base install for you?
from pure-lang.
@rebcabin can you try sudo apt -f install
and sudo dpkg --reconfigure -a
, then sudo apt clean && sudo apt update && sudo apt install pure-base
?
from pure-lang.
I get the same dependency error when trying to install pure-complete too, with 18.10 (Cosmic), but pure-base
works fine.
from pure-lang.
I confused the packages. pure-base
installs; pure-complete
errors due to pure-web
and pure-math
.
I think I have found the fundamental issue though, which is that libmpfr4
is now a (virtual / meta)package and can't be installed alone.

It seems that, at least for me with 18.10/cosmic, it has been obsoleted and the package renamed:

libmpfr-dev/cosmic,now 4.0.1-1 amd64 [installed]

However, sudo apt-get install pure pure-docs works.

@catb0t thanks for sorting that out. These dependencies on libmpfr4 are all auto-generated by debuild, so it looks like I'll just have to regenerate a new revision of both pure-mpfr and pure-fastcgi and everything should be fine again.
This makes sense because I made those builds quite a while ago (Jan 2018) when Bionic wasn't released yet. The reason that it works on my system is that I do still have libmpfr4 installed, apparently that's left over from that early iteration of Bionic.
I don't understand why the Cosmic packages in https://launchpad.net/~dr-graef/+archive/ubuntu/pure-lang.cosmic wouldn't work, though. I've built these fairly recently, after the release of Cosmic, and I just checked the deps, they do depend on libmpfr6, not libmpfr4.
from pure-lang.
Should be fixed now, just built new packages for Bionic, can you please test?
from pure-lang.
I now see what the problem on Cosmic is, pure-octave still has an out-of-date dependency on octave40 there, will fix that later today.
from pure-lang.
Cosmic should be fixed now as well, please test.
from pure-lang.
Confirming fixed for .bionic
and .cosmic
PPAs, thank you!

@catb0t thanks for testing!
