Why this dpkg error: ambiguous package name 'libglib2.0-0' ...?
I have some weird errors while trying to install packages with software center or even when I try to upgrade packages with sudo apt-get install upgrade:
dpkg: error: file triggers record mentions illegal package name `libglib2.0-0' (for interest in file `/usr/lib/x86_64-linux-gnu/gio/modules'): ambiguous package name 'libglib2.0-0' with more than one installed instance
Previously I had error:
dpkg: error: configuration error: /etc/dpkg/dpkg.cfg.d/multiarch:1: unknown option 'foreign-architecture'
but I have just removed it with: sudo rm /etc/dpkg/dpkg.cfg.d/multiarch, I guess this post describes this issue - I have followed it, but the last part sudo apt-get install dpkg=1.16.0.3ubuntu5 did not work for me - no such package could be found. Probably it is because I am using ubuntu 12.04.
UPDATE: adter trying to installcorrect version of dpkg 1.16.1.2ubuntu7 as suggested in the answer, I now get following errors:
$ sudo apt-get install dpkg=1.16.1.2ubuntu7
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
ia32-libs : Depends: ia32-libs-multiarch but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
By the way, this might be also helpful:
$ sudo dpkg --configure -a
dpkg: error: file triggers record mentions illegal package name `libglib2.0-0' (for interest in file `/usr/lib/x86_64-linux-gnu/gio/modules'): ambiguous package name 'libglib2.0-0' with more than one installed instance
which is actually telling the same thing.
UPDATE: content of (...) modules:
/usr/lib/x86_64-linux-gnu/gio/modules$ ls
giomodule.cache libgiognutls.so libgvfsdbus.so
libdconfsettings.so libgiolibproxy.so
libgiognomeproxy.so libgioremote-volume-monitor.so
UPDATE: /var/lib/dpkg/triggers/File
$ sudo grep libglib /var/lib/dpkg/triggers/File
/usr/lib/x86_64-linux-gnu/gio/modules libglib2.0-0
/usr/lib/gio/modules libglib2.0-0
/usr/share/glib-2.0/schemas libglib2.0-0
/usr/lib/i386-linux-gnu/gio/modules libglib2.0-0:i386
/usr/lib/gio/modules libglib2.0-0:i386
/usr/share/glib-2.0/schemas libglib2.0-0:i386
no such package could be found. Probably it is because I am using ubuntu 12.04.
The corresponding version for Ubuntu 12.04, as of this date, should be 1.16.1.2ubuntu7.
ia32-libs : Depends: ia32-libs-multiarch but it is not installable
This is a link to the ia32-libs-multiarch page, where you can download the .deb file. Please use dpkg -i filename.deb to manually install it, and if successful, try apt-get again. If not, please update with dpkg error.
I installed ia32 on a test x86_64 system, and got the following for the contents of the triggers File and the contents of giomodule.cache. Please check to see how yours differ:
izx@myprecise:~$ grep libglib /var/lib/dpkg/triggers/File /usr/lib/x86_64-linux-gnu/gio/modules libglib2.0-0 /usr/lib/gio/modules libglib2.0-0 /usr/share/glib-2.0/schemas libglib2.0-0 /usr/lib/i386-linux-gnu/gio/modules libglib2.0-0:i386 /usr/lib/gio/modules libglib2.0-0:i386 /usr/share/glib-2.0/schemas libglib2.0-0:i386 izx@myprecise:~$ ls /usr/lib/x86_64-linux-gnu/gio/modules giomodule.cache libgiognutls.so libgvfsdbus.so libdconfsettings.so libgiolibproxy.so libgiognomeproxy.so libgioremote-volume-monitor.so izx@myprecise:~$ cat /usr/lib/x86_64-linux-gnu/gio/modules/giomodule.cache libgiognutls.so: gio-tls-backend libgioremote-volume-monitor.so: gio-native-volume-monitor,gio-volume-monitor libgvfsdbus.so: gio-vfs,gio-volume-monitor libgiolibproxy.so: gio-proxy-resolver libdconfsettings.so: gsettings-backend libgiognomeproxy.so: gio-proxy-resolver
I had the exact same issues.
I removed the line
/usr/lib/gio/modules libglib2.0-0
from /var/lib/dpkg/triggers/File
Although being a bit of a novice, I'm not sure it was a good idea or not, but it at least removed the error so I could continue.
