I’d like to add support for the “aptitude safe-upgrade” command in an ansible module. I was thinking of one of two options for implementing it: Option 1: Modifying the apt module so that the “upgrade” parameter can take a new argument, e.g. “safe”: (apt: upgrade=safe). In this case, it would do “aptitude safe-upgrade -y” Option 2: Adding a new “aptitude” module. I’d prefer option #1, but I wanted to hear if others felt differently. Note that the difference between “apt-get upgrade” (apt: upgrade=yes) and “aptitude safe-upgrade” is that “aptitude safe-upgrade” will install missing dependencies. Lorin ---

Why would you ever not want to install new dependencies added by a package upgrade? Seems like if you wanted to, you could just use the command module for this, but it also seems very strange. If a package goes from v1 to v2 and now requires X, it seems not installing X is not safe in the least 🙂 ---

​safe-upgrade should be the default. regular upgrade is more of what is used for distribution upgrades. as per: [http://askubuntu.com/questions/117088/aptitude-safe-upgrade-equivalence-with-apt-get](http://askubuntu.com/questions/117088/aptitude-safe-upgrade-equivalence-with-apt-get) The apt-get command closer to aptitude safe-upgrade is upgrade, but there is a difference. aptitude safe-upgrade upgrades currently installed packages and can install new packages to resolve new dependencies, but never removes packages. apt-get upgrade upgrades currently installed packages, but never installs or removes packages. So apt-get upgrade is comparable to aptitude --no-new-installs safe-upgrade. ​ ---

OK, I will modify the behavior of “apt: upgrade=yes” to use “aptitude safe-upgrade” instead of “apt-get upgrade” Lorin ---

No, it's correct. "aptitude safe-upgrade" installs missing dependencies, and "apt-get upgrade" doesn't. You pretty much always want to install missing dependencies if an updated package requires a new dependency, so "aptitude safe-upgrade" is the common case. Lorin ---

This is merged now. As we are scheduled to release 1.1 tomorrow, if everyone can test the app module today that would be greatly appreciated! ---

How would this run for systems which only have apt-get installed and not aptitude? ---

(A) You could of course install aptitude. (B) I think the real question you meant to ask was 'can we do this with apt instead', which is my question. Though it will need to wait until 1.2.
