Summary

bind has a warning during uninstall:

# tdnf remove -y bind
<snip>

Removing: bind-9.20.5-1.azl3.x86_64
/var/tmp/rpm-tmp.o0lrpa: line 12: Vendor:: command not found
/var/tmp/rpm-tmp.o0lrpa: line 13: Distribution:: command not found
warning: %postun(bind-9.20.5-1.azl3.x86_64) scriptlet failed, exit status 127
package bind-9.20.5-1.azl3.x86_64: script warning in %postun

The issue is that we we're missing a new-line at the of the %postun scriptlet, which makes the Vendor: and Distribution: lines sneak into that script, which means bash tries to run them as programs. Interestingly, if you drop an executable file at, say, /usr/bin/Vendor:, this will run it. Fun.

This has been there for years and as it happens both the Vendor: and Distribution: lines were duplicates of the ones towards the top of the file so just deleting them and making sure we have the blank line fixes things.

Change Log

• Remove spurious Vendor: and Distribution: lines.
