DOH! the fix somehow didn't make it to the push to the tree.  I had found this same error during my initial bumping.  The plugin.cache is not re-generated in the build environment when upgrading from older autobahn.  When re-installing, it is generated.  Instead I had re-directed output to /dev/null so it would ignore a failure to rm the file before install as it may not exist.   If it did fail, but did exist, then the install would fail due to a file collision.

Pushing the fixed ebuild to the tree.  Please re-test to confirm.

Actually I think the plugin.cache is only generated when you enable tests. As it more fully integrates with twisted than it did in previous versions.

No, the image does not have FEATURES=test and I really try to double-ensure it for non-test tinderbox images:

[Comment 10 Brian Dolbec (RETIRED) 2020-05-10 08:59:51 UTC]

Yes,  since you did not enable tests, the plugin.cache was not generated to run the tests.  So when it tried to rm the non-existent file, it failed due to the " | die" tacked on to the command.  I missed seeing the fix was missing when I pushed the bump to the tree.

The ebuild now just re-directs the output to /dev/null for that rm command.  So it won't matter if the file existed or not.  If it did it would remove it to prevent a file collision with twisted's plugin.cache which is re-generated in postinst.

Seems to be no other reports of this still occurring... closing
