** Description changed:
+ [Impact]
+
+ * Upgrade from Bionic to Focal may break
+ * The upload really forces
+
+ [Test Case]
+
+ $ lxc launch ubuntu:bionic bb-glibc-upgrade
+ $ lxc shell bb-glibc-upgrade
+ # export LDCONFIG_TRIGGER_DEBUG=1
+ # apt update -qq && apt upgrade -qq -y && do-release-upgrade -d
...
- if [ -n "$preversion" ] && dpkg --compare-versions "$preversion" lt
2.31-0ubuntu2; then
- LCONFIG_NOTRIGGER=y
+
+ With the broken version the following message can be observed:
+ ..
+ Preparing to unpack .../libc6_2.31-0ubuntu9_amd64.deb ...
+
+ Progress: [ 38%]
+ ldconfig: wrapper deferring update (trigger activated)
+ ...
+
+ The fixed version runs ldconfig immediately after unpacking libc6.
+
+
+ [Regression Potential]
+
+ * Very small, the fix is literally adding one single character to
+ properly set LDCONFIG_NOTRIGGER.
+
+ [Other Info]
