I've tried the "c" (catchup) command, but that didn't help.

The zero-length files were easy enough to find, and few enough
that I just deleted them by hand.  No luck.  I've even tried
deleting the entire contents of a group, e.g.:

rm /var/spool/slrnpull/news/linux/debian/user/*

Still no luck.  The group header window still shows the number
of messages that were available; the "c" command resets this to
zero, but I still get "Server read failed." when trying to enter
the group.

Oddly enough, there are one or two groups which are still
working properly.

I was hoping that there was an slrn guru who could explain all this.

Oh well, I've been meaning to upgrade my laptop to Bullseye -
maybe it's time to nuke slrn and re-install it from scratch.

  if you have a file which keeps track of what you have already
read like .jnewsrc there are lines in there for groups you've
subscribed to which keep track of which articles you've read.
after you delete the files from your spool then you would also
need to change the lines back so that you could read them
again.

here's an example of two lines in my .jnewsrc file that show an
example:

rec.food.cooking: 1-253560
rec.food.cuisine.jewish!

the first line says what articles i've seen and the second is
an example of a group i've not read any messages from at all.
so if you change the lines of groups you'd like to reread back
to ! marks then you should be able to redownload them.  you
may need to resubscribe to them.

  you can uninstall it but that may not clear up the spool for
the groups, so you'd need to see if that actually works or not.
