I am running Linaro 12.04 LTS. Nearly every time I try to use (sudo) apt-get, the process ends unsuccessfully with the message uboot-mkimage : Depends: u-boot-tools but it is not installed . I tried to load u-boot-tools and that did not work either: > sudo apt-get install u-boot-tools Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: u-boot-tools 0 upgraded, 1 newly installed, 0 to remove and 24 not upgraded. 1 not fully installed or removed. Need to get 0 B/51.7 kB of archives.

Anyone else come across this issue and find an answer? Thanks.
