Updated to 20170529 and found that acroread does not work anymore. Tried to reinstall and got the message:
erlangen:~ # zypper in acroread

Problem: nothing provides ISO8859-1.so needed by acroread-9.5.5-8.1.i586
Solution 1: do not install acroread-9.5.5-8.1.i586
Solution 2: break acroread-9.5.5-8.1.i586 by ignoring some of its dependencies

Yes, for several years I checked out okular and everytime I noticed that even on modern hardware it took considerable time to display a single page. Thus I preferred acroread which was really fast. I checked again with okular-17.04.1-1.2.x86_64 and found displaying a page has become faster. But I think okular is still sluggish compared to acroread. Are there any other pdf readers available with better speed?
Likely dozens, qpdfview, xpdf, evince, ghostview come to (my) mind, for more you can do your own (re)search.
Using acroread for speed reasons (which I find funny as it always has been an ugly and giant blob) is certainly the worst idea as this piece of software has been unmaintained for several years now and is a huge security risk (not mentioning the non-security bugs).
Hi
Run ldd against the acroread binary to see where/what it’s looking for… ahh it’s 32bit glibc-locale-32bit. You might need to create a softlink. But I would strongly suggest an alternative, if that’s not working as required create a bug report…
So the problem is not some missing/removed file but an obsolete “Requires” inside the acroread RPM which explicitly requires “ISO8859-1.so” instead of glibc-locale(x86-32).
Forget the bug report then (and get rid of that Adobe plague ASAP), acroread has been removed from official repos years ago, so most likely the maintainers of the official distro repos will not fix that.
Indeed, and worst of it, a very old and non-maintained mess which nobody except Adobe could fix.
As you said in your first post, acroread did not start, you removed it and got that error from zypper when trying to reinstall.
However, as the file is there, it is quite likely the problem why acroread will not start any more lies somewhere else and has nothing to do with the (now) misplaced explicit requirement zypper complains about.
In this case, it certainly will be.
Just ran that update inside a VM and certainly zypper has become a lot faster when installing packages.

Zypper is fast when there is nothing to do and it was fast to figure out that 2609 packages needed to be installed. Actually I noticed no difference.
