[Bug 1940503] Re: Illegal instruction (core dumped) on apt update

[John Freeman]

This appears to be a duplicate of
https://bugs.launchpad.net/ubuntu/+source/command-not-
found/+bug/1876034. It may be worth holding off using the "Mark as
duplicate" function as it hides the duplicate from the search results.
Since 1876034 doesn't contain the error the end-user sees (this bug
report does), it would be easy to miss there's an existing issue raised
(and already one other bug report marked as duplicate).
