Again truecharts does not build the nextcloud container. Any limitations on apt/apt-get (or the alpine equivalent for alpine based containers) comes from the upstream source. In this case nextcloud it's self.
And despite.my better judgement. apt-get should work fine from the normal nextcloud shell, I just tested it on my test box.. But thanks to a bug from ix the first time you connect even when you select the nextcloud pod it goes to the hpb (where apt-get won't work). You have to hit reconnect then again select the nextcloud pod. Not that I would ever recommend doing something as foolish as using apt-get inside of nextcloud or any non persistent container that's just going to get wipedout the next container download. Also the proper nextcloud pod includes nano if that's what your after.
Just don't go complaining if you break your install
Apt-get would be to install nano.
Nano would be installed to edit a file (in this case, php-fpm.conf
Php-fpm.conf contains pretty important settings that even nextcloud claims is incorrect in your deployment.
And I don't complain when I break my install... If I break it, I either know how to fix it, or I'm willing to reinstall or at worst, start from scratch.
<Removed comment about hpb, I can't find strikethrough on my phone, so... Just removed it>
and, while I appreciate the insight, it's. It really helpful to constantly deflect everything as not being Truecharts fault. You guys have (from my point of view) attempted to deflect any and all blame. If it doesn't work, you blame TrueNAS... Or upstream. Seems like nothing is ever the fault of Truecharts...
