I am running Ubuntu Linux 14.04 via Parallels (10.1.4) in Mac OS X 10.10.2 on a MacBook Pro. Today I received update notifications for Ubuntu (first) and then Parallels and stupidly installed them (I never learn; I have problems every time).
Now when I open
gnome-terminal (not the Mac Terminal, the Ubuntu one), I have no command-line prompt. So I can't use
gnome-terminal. I have tried reinstalling Parallels tools, but nothing changes.
I don't know whether the Parallels or Ubuntu update created the problem, but I suspect it was the Ubuntu update. After a few minutes, the following error appears in a terminal:
Unknown processor type for Linux bash : [: -eq: unary operator expected Your "" operating system is not supported by this release of XXX.
XXX is a program I use via Parallels.
Is there a way to undo the update without having to reinstall the virtual machine and/or Ubuntu? I don't want to lose my current setup; it took ages to get right. I would be grateful for any advice.
