+## Upgrade to latest stable
+
+Enure backups !
+
+### Ensure everything is up to date
+
+```shell
+apt-get update
+apt-get upgrade
+apt-get dist-upgrade
+```
+
+### Check package db consistency
+
+```shell
+dpkg -C
+```
+
+### Check hold packages
+
+Hold packages will not be upgraded, ensure there is no deps shit
+
+```shell
+apt-mark showhold
+```
+
+If there is anything, check with `dpkg --audit`
+
+### Update source list
+
+Check
+
+```shell
+sed s/$OLDSTABLE/$STABLE/g /etc/apt/source.list
+# for exemple
+sed s/stretch/buster/g /etc/apt/source.list
+```
+
+Is it's ok, go
+
+```shell
+sed -i s/stretch/buster/g /etc/apt/source.list
+```
+
+Do not forget stuff in source.list.d
+
+```shell
+find /etc/apt/sources.list.d/ -type f -exec sed -i s/stretch/buster/g {} \;
+```
+
+### Simulate
+
+```shell
+apt update
+apt --list upgradable
+```
+
+### Go
+
+```shell
+apt-get upgrade
+apt-get dist-upgrade
+```
