Update stops at "eglibc (2.13-7) unstable; urgency=low"

Postby setcho on Thu Jun 23, 2011 9:45 am

Hi,

I decided to try out Mint debian gnome edition yesterday and I came across a problem. First there was the "Could not apply changes fix broken packages first", so I ran sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist upgrade.
This starts to work but then stops at the following message in the terminal

eglibc (2.13-7) unstable; urgency=low

Starting with version 2.13, eglibc provides an SSSE3 optimized version
of memcpy() on the amd64 architecture. This version might copy memory
backward in some conditions, which causes issues if the source and
destination overlap. memmove() should be used in such cases, but some
programs still wrongly use memcpy().

For this reason, on the amd64 architecture the Debian package provides
two wrappers which can be use to workaround and/or debug the issue:
- /usr/lib/x86_64-linux-gnu/libc/memcpy-preload.so simply replace all
calls to memcpy() by a call to memmove()
- /usr/lib/x86_64-linux-gnu/libc/memcpy-syslog-preload.so does the same,
but in addition logs (with rate limit) the issue to syslog, so that it
can be detected and fixed.

To use these wrapper on a single binary, the easiest way is to use the
LD_PRELOAD environment variable:
- LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libc/memcpy-preload.so /path/to/binary
- LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libc/memcpy-syslog-preload.so /path/to/binary

For system-wide usage, it is possible to add the path of one of the
/tmp/tmp_2nhQS

When I came across this yesterday I closed the terminal, restarted then ran the above update command again. This seemed to do the trick and everything updated however after another restart there was something very wrong. Mint menu had disappeared and Mint Icons and Login screen were both non-mint (i mean that it looked like it had fallen back to a more basic debian style). So I tried to add another menu and it wouldn't work, i tried to restart but couldn't, in the end I had to power off.

Anyway I thought I would try a clean install today and if I came across the same problem I would ask before I proceeded beyond this screen, so here I am asking :)

Thanks

When updating using the MintUpdate utility that package created a popup window with the same changelog message as you received in terminal. The only option the popup window had was a close button. I have seem comments in the LMDE breakage thread suggesting that once the terminal has reached the end of the output you press q instead of closing the terminal.

The way round that worked for me (several times) - when the terminal stops, close it normally, open and run update manager. This should install the already downloaded packages. Hope this may help you! Will try "q" next time a problem is encountered.

Impatience got the better of me and I cancelled out of this screen again and then tried all the commands posted here http://forums.linuxmint.com/viewtopic.php?f=46&t=73931&p=429676&hilit=eglibc#p429676 in order to fix the broken packages problem. It seemed to work as after the terminal was finished I was able to use update manager to install the rest of the updates.

I'm going to try LMDE Xfce over the weekend so if I run into this problem again I will try q in the terminal however I will try to fix the broken packages problem first (if it comes up) by using the method outlined in the above post so hopefully I will bypass the "eglibc" screen altogether.

Thanks for the replies and I will report back on what happens.

I installed LMDE xfce and there was no fix broken packages update problem however during the update process the eglibc screen does appear but it can be closed with the close button just as dawgdoc mentions above.

So all is well and I will be sticking with the xfce version for now.
