1Report a reason when a dependency could not be installed because it is locked
2
3If a requirement of a package is conflicted, depending on how the
4solution is reached, the transaction code may eliminate all providers
5of the requirement and then error out because nothing provides them. To
6work around this, store a reason in the locked dict and report that back
7if we need to, so for example instead of:
8
9 error: Can't install packagegroup-core-ssh-dropbear-1.0-r1@all: no package provides dropbear
10
11we now get:
12
13 error: Can't install packagegroup-core-ssh-dropbear-1.0-r1@all: unable to install provider for dropbear:
14 error: dropbear-2013.58-r1.0@armv5te is conflicted by openssh-sshd-6.2p2-r0@armv5te
