* cups-filters is a former part of cups that provides file format conversions |
| 12 |
(among other things). Basically it (also) makes sure that everything is |
| 13 |
internally converted to PDF. It's not part of CUPS (as maintained by Apple) |
| 14 |
anymore, but hard-required by CUPS on Linux (and maintained by the Linux |
| 15 |
Foundation). |
| 16 |
|
| 17 |
* foomatic-filters is a set of printer drivers, basically. |
| 18 |
|
| 19 |
* Some time ago the cups-filters maintainers took over maintainership of the |
| 20 |
foomatic-filters part for CUPS as well, and integrated it cleanly into cups- |
| 21 |
filters. That's the reason for the blocker; recent cups-filters contain the |
| 22 |
newest foomatic code available. The former separate foomatic-filters package |
| 23 |
is now unmaintained. |
| 24 |
|
| 25 |
So, we have the following possibilities for installation: |
| 26 |
|
| 27 |
1) normal CUPS user, recommended, this is what comes by default (unless you do |
| 28 |
something stupid such as USE="-*") |
| 29 |
net-print/cups |
| 30 |
net-print/cups-filters[foomatic] |
| 31 |
|
| 32 |
2) NOT recommended, dead code, unmaintained: |
| 33 |
net-print/cups |
| 34 |
net-print/cups-filters[-foomatic] |
| 35 |
net-print/foomatic-filters |
| 36 |
|
| 37 |
3) for the stone age people out there, NOT recommended, dead code, |
| 38 |
unmaintained: |
| 39 |
any other printing system, e.g. lprng |
| 40 |
net-print/foomatic-filters |
| 41 |
|
| 42 |
So, what's wrong in your case? No idea, but after longish not-updating things |
| 43 |
do get hard for emerge to unravel. My recommendation is, since foomatic- |
| 44 |
filters and cups-filters are only needed for printing and emerge runs fine |
| 45 |
without them, force-remove both and let emerge figure out the right package |
| 46 |
set from scratch. |
| 47 |
|
| 48 |
[This basically works with any blocker as a last resort, but can be *very* |
| 49 |
dangerous for packages that are needed by the core system. You definitely |
| 50 |
don't want to remove gcc or glibc this way, for example. :)] |
| 51 |
|
| 52 |
emerge -aC net-print/cups-filters net-print/foomatic-filters |
| 53 |
emerge -uDNavt --backtrack=100 world |
| 54 |
