I'm (still) on Debian Squeeze. When I try to upgrade the system, here's what I get:
[09:20]/root# aptitude upgrade No packages will be installed, upgraded, or removed. 0 packages upgraded, 0 newly installed, 0 to remove and 1 not upgraded. Need to get 0 B of archives. After unpacking 0 B will be used.
Looking at the log, I get a hint at the name of the culprit package:
Aptitude 0.6.3: log report Sat, Jun 22 2013 09:20:13 +0200 IMPORTANT: this log only lists intended actions; actions which fail due to dpkg problems may not be completed. Will install 0 packages, and remove 0 packages. =============================================================================== [HOLD] libxcb1 =============================================================================== Log complete.
However, if I look at the package, I don't get any more details:
[09:21]/root# aptitude show libxcb1 Package: libxcb1 State: installed Automatically installed: no Version: 1.6-1 Priority: optional Section: libs Maintainer: XCB Developers <email@example.com> Uncompressed Size: 188 k Depends: libc6 (>= 2.3.2), libxau6, libxdmcp6 Breaks: libxcb-xlib0 ...
I'm surprised by how little info
aptitude is giving me about its refusal to upgrade the package.
My question is: What are the steps I should follow in this situation to find out why this package is not upgraded?
Update: Here's the desired command:
$ apt-cache policy libxcb1 libxcb1: Installed: 1.6-1 Candidate: 1.6-1+squeeze1 Version table: 1.6-1+squeeze1 0 500 http://security.debian.org/ squeeze/updates/main amd64 Packages *** 1.6-1 0 500 http://debian.mirrors.ovh.net/debian/ squeeze/main amd64 Packages 100 /var/lib/dpkg/status
