+# playbook - ubuntu dist-upgrade
+
+upgrading ubuntu and managing configuration file changes, you might also want to use tools such as [etckeeper](https://etckeeper.branchable.com/)
+
+## upgrade using `do-release-upgrade`
+
+```shell
+DEBIAN_FRONTEND=noninteractive do-release-upgrade
+```
+
+## post-upgrade: manage configuration file changes
+
+### locate all changed configuration files
+
+- **for `.dpkg-*` files:**
+
+```shell
+find /etc -name "*.dpkg-*"
+```
+
+- **for `.ucf-dist` files:**
+
+```shell
+find /etc -name "*.ucf-dist"
+```
+
+### compare and merge changes
+
+- use `vimdiff` or a similar tool to compare the original file with the new version:
+
+```shell
+vimdiff /path/to/config.file /path/to/config.file.dpkg-dist
+vimdiff /path/to/config.file /path/to/config.file.ucf-dist
+```
+
+### remove temporary files
+
+- once resolved, delete `.dpkg-*` and `.ucf-dist` files:
+
+```shell
+rm /path/to/config.file.dpkg-dist
+rm /path/to/config.file.ucf-dist
+```
