A sarge->etch upgrade does not enter into it to me; my laptop has had
etch installed from the time I bought it (early June), and still has the
broken symlink that I described.

The problem seems to be due to different terminal emulators registering
slave symlinks with different names for x-terminal-emulator.

x-terminal-emulator.1x.gz \
xterm.postinst: /usr/share/man/man1/x-terminal-emulator.1x.gz 
x-terminal-emulator.1x.gz \

This inconsistency causes a broken symlink if the alternative is
changed:

The machine no longer exists, but on another one, I've just changed the
x-terminal-emulator alternative from /usr/bin/xfce4-terminal.wrapper to
/usr/bin/uxterm, and I also get a dangling symlink.

ay:~> ll /usr/share/man/man1/x-terminal-emulator.1.gz
lrwxrwxrwx 1 root root 42 2003-07-18 22:14:13 
/usr/share/man/man1/x-terminal-emulator.1.gz -> 
/etc/alternatives/x-terminal-emulator.1.gz
ay:~> ll /etc/alternatives/x-terminal-emulator.1.gz
ls: /etc/alternatives/x-terminal-emulator.1.gz: No such file or directory

But there's the following symlink:

lrwxrwxrwx 1 root root 32 2006-11-08 02:45:07 
/etc/alternatives/x-terminal-emulator.1x.gz -> /usr/share/man/man1/uxterm.1x.gz

This is with xterm 210-3.1 (from testing).

ok, so when different alternatives for the same command have different
slaves, update-alternatives seems to badly handle the situation. In this
case, it doesn't change the link from
/usr/share/man/man1/x-terminal-emulator.1.gz to /etc/alternatives, only
the link in /etc/alternatives to /usr/share/man/man1/whatever-term.1.gz.

The solution for this is probably to have the same slave as other
terminal emulators (revert to x-terminal-emulator.1.gz), and somehow
handle the upgrade from previous versions of xterm, if necessary.
I'll try to implement and test this for the next xterm upload.

Thanks,
Julien

Hi,

I tried to reproduce this by upgrading xterm from sarge to etch and
didn't get any dangling symlink.  I tried an upgrade with xterm as the
only x-terminal-emulator package installed, as well as with xterm and
rxvt, and I also tried setting the link to uxterm manually before the
upgrade.  This choice seems to be lost on upgrade (probably due to the
path change for *xterm), but I got no dangling symlink.
I'd appreciate your help in trying to understand how things went wrong
for you, and if it's still possible for them to go wrong in case of a
sarge->etch upgrade.

Thanks,
Julien

The problem is still there in xterm 210-3.
