[Bug 1693447] [NEW] package libc-bin 2.23-0ubuntu7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[atul vaish]

Public bug reported:

installing selinux led me to this and  my 16.04 ubuntu during normal
boot up lands at "low graphics mode" . now selinux has been removed,
though I get this error and even "low graphics mode" issue not going
away  (as a workaround , boot up via grub-->recovery-->enable network
stack-->do a normal resume, get me my system back) .

tried almost all methods to remove low graphics mode , but not success.
