[Bug 1875224] [NEW] gcc-7-multilib : Depends: gcc-7-base (= 7.4.0-1ubuntu1~18.04) but 7.5.0-3ubuntu1~18.04 is to be installed

[Steven Welch]

Public bug reported:

Ubuntu 18.04 HWE is currently not allowing installation of
gcc-7-multilib, which is a requirement for me to install rocm-dkms and
rocm-dev and hcc for my Radeon cards.  There's some kind of version
mismatch between gcc 7.4 and 7.5 happening.  The packages "gcc-7" and
"gcc-7-base" are currently installed just fine, however.  The error is
as follows:

$ sudo apt install gcc-7-multilib
Reading package lists... Done
