I can't understand the /tmp issue either. This is from /etc/fstab :

none /tmp usertemp binary,nouser,posix=1 0 0

No good idea.

My upgrade path was

5.3.5-1 -> 5.3.6-1 -> 5.3.6-2

Trying to follow manually

# /usr/sbin/alternatives --install /usr/bin/lua lua /usr/bin/lua5.3 503 --verbose --test
reading /var/lib/alternatives/lua
auto
/usr/bin/lua

/usr/bin/lua5.3
503
would link /usr/bin/lua -> /etc/alternatives/lua
would link /etc/alternatives/lua -> /usr/bin/lua5.3

It seems "alternatives" is trying to create links to nonexistent files.
Which is not possible under Windows.

Manually creating source link let the thing go

# ln -fsT /usr/bin/lua5.3 /etc/alternatives/lua
# /usr/sbin/alternatives --install /usr/bin/lua lua /usr/bin/lua5.3 503 --verbose
reading /var/lib/alternatives/lua
