** Description changed:
- I was upgrading from Bionic to Cosmic when I received a conffile prompt
- regarding /etc/update-initramfs/initramfs.conf, I clicked keep and then
- saw this Traceback:
+ [Test Case]
+ 1) Ensure the following packages from -updates (version
0.52.2-1ubuntu1~18.04.1) are installed on an Ubuntu 18.04 system:
gir1.2-vte-2.91 libvte-2.91-0 libvte-2.91-common
+ 2) Modify /etc/issue e.g. I changed 18.04 to 18.04.2
+ 3) Ensure /etc/update-manager/release-upgrades contains "Prompt=normal"
+ 4) Run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk -d
+ 5) When prompted about replacing "the customized configuration file
'/etc/issue'" click Keep
+ 6) Observe a traceback in Vte.Terminal.feed_child()
+
+ After installing the new version of vte2.91 in -proposed you should no
+ longer receive a Traceback when clicking keep during the upgrade
+ process.
+
+ [Regression Potential]
+ Per laney: "The regression potential is that I messed up the upload and
everything using feed* breaks."
+
+ It'd probably be good to test guake too since it uses feed_child().
