Wes,<\/p>\n

Yesterday morning \/etc\/cron.daily\/apt applied a libc update to morpho. While that shouldn’t have caused a problem, it might have. \u00a0NetWorker is not working (it throws an invalid pointer error in munmap_chunk() which is in glibc). \u00a0I have upgraded the NetWorker client to 8.1.1.7 (the latest and greatest) but it still is failing. \u00a0EMC would like us to reboot the system because it might resolve the issue.<\/p>\n

Is there any particular time that a reboot would be better or worse? Are you ok with me (or someone from SAA) rebooting the system?<\/p>\n

If nothing is running, ok to reboot<\/p>\n

Hi Wes,<\/p>\n

I took a look at morpho and it appears that the system is somewhat
\nbroken. \u00a0A glibc upgrade has occurred which seems to break ABI, but
\nthere are some packages which are held back (I presume they were copied
\nand installed by hand) which are preventing the system from finishing
\nits install.<\/p>\n

There are various suggestions that aptitude is making to resolve the
\npackage state: \u00a0removing libreoffice, removing openoffice, or removing
\nbbb (followed by an install of a more updated version?) \u00a0might get the
\nsystem into a better state.<\/p><\/blockquote>\n

Why does all this happen while I’m on vacation? I’m on a farm in southern canada armed with an iPad and < 200mb remaining on my at&t international data plan. Why do I keep reading email?<\/p>\n

Most recent bigbluebutton is .81. That's what is installed. Libreoffice is a bbb dependency. I don't think OpenOffice is installed, but it might be left over from a previous bbb install, in any case it has been superseded by libreoffice and is no longer required.<\/p>\n

I suppose bbb can be removed and reinstalled, although there are a handful of undocumented site specific configuration files that might get overwritten, thus rendering bbb useless.<\/p>\n

So what to do? Remove all XOffice, reinstall libreoffice , don't mess with bbb unless we really have to? Regress to earlier glibc? Wait until I get back (aug. \u00a018)?<\/p>\n

It looks like bbb is still working, which is very surprising to me,
\nsince the glibc breakage is so bad that we can’t run scp or iptables.<\/p>\n

Maybe it can wait until the 18th, but it probably shouldn’t wait any
\nlonger because you might have to recover from backups to fix this
\nparticular problem. \u00a0(That’s a bare-metal restore, BTW, since ‘recover’
\non morpho is also badly broken.)<\/p><\/blockquote>\n

Mike and I tested it and, astonishingly, BBB is still working (we shared
\na 2-person videoconf.) \u00a0If you are comfortable waiting until you are
\nback on the 18th to look at it, that’s up to you. \u00a0Mike and I are both
\non vacation the week of the 18th, so assistance from SAA that week may
\nnot be as timely.<\/p><\/blockquote>\n

Found this:<\/p>\n

Seemed to work. apt-get working now, scp too.<\/p>\n

Included with latest upgrade was bbb-client update<\/p>\n

https:\/\/groups.google.com\/forum\/m\/#!topic\/bigbluebutton-setup\/db8VxAn_iaY<\/p>\n

Which should not break anything,but I don’t have the equipment to test.<\/p>\n

How many points do I win for fixing this?<\/p>\n
