I've attached a patch file.

AIUI it is better to specifically path /bin/bash rather than via env,
escpecially when we know for sure where bash is located....

- save [with verbose] orig sources.list (mv -v)
- save file permissions and timestamps [with verbose] with cp (cp -vp)
- adjust sed to use more normal "sed -i" form...?
- indent cat EOF (better readability).

Also fix http:// ref to https:// with a server that is valid.



Not tested.... not sure if /etc/network/interfaces change is universal
or not.

Perhaps change line 7 for which vim instead of vim.tiny?

Also, if the keyring package (.deb file) is "stable", why not verify
it's checksum?

Passes shellcheck cleanly.

Cheers
A.
