[Cbc] [External] Re: 2.10 version on Ubuntu

[Ted Ralphs]

Yes, the uninstall should be done as sudo if the installation directory is
not writable by the user. I now added a check and it will automatically
prompt you for a sudo password if you forget to run it as sudo and this is
needed. The same is actually true for the install, so there is technically
no need to run anything as sudo.

I've detected a few more bugs for some uncommon edge cases, so better do an
update. I hope it will be stable soon and then I will start making releases
and do enhancements in separate feature branches so it's not such a
moving target.

Cheers,

Ted
