Does the appended LyX file do what you want? I used the alignat environment,
and increased the number of columns to five. The left side of each
inequality goes in column 1, the inequality symbol in column 2, the right
side in column 4 and the iff symbol in column 5. Column 3 is intentionally
blank.


I came up with a (not so clean) solution:

You'll probably have trouble installing any package, not just LyX.
Something went amiss with the libreoffice builds. Either remove the
offending packages, or try to update 'apt' and then upgrade the
package (assuming updates are available).

[John Kane]

I don't know what I had running but I did a shut-down before going shopping
and after a reboot and something is happening. Thanks

 My problem is that I removed libreOffice to install Apache OpenOffice so I
don't really under stand what the output is telling me. Why would a removal
of LyX depend on some missing LibreOfice files?

This happens if at the same time some other package management tool is 
running and holds a lock on the database. Assuming that you don't do that 
yourself, the most likely reason is an automatic 'apt-get update' running in 
the background from cron. You would see the process in the output of

ps -axu | grep root

and usually it would not take long to be finished, so you could try again.

Following up on my last post

You might want to run 'apt-get -f install' to correct these.

Any suggestions would gratefully received.

centered formulas + \iff

[Kiuhnm]

Hi,

I'm using Lyx 2.1.4. I'd like to write a bunch of inequalities with an 
\iff on the right side. The inequalities should be centered, like this:

 <=>
 <=>
<...>
The problem with gather is that it only allows one column. If I insert a 
gathered environment and add a second column, it doesn't work.


Wouldn't it be simpler if Lyx let users decide the horizontal alignment 
on a column-by-column basis? I guess there are technical difficulties in 
doing this...

Are you root? These should be run under root or with sudo.
