noapt

Is a small wrapper around plash, that lets you install ubuntu packages in your home folder. It does not acutaly need an ubuntu system and it can be used by non-privileged users.

Install

pip3 install noapt --user

Example

$ noapt

$ noapt git

How does that work?

noapt itself is just ~50 lines intense but comparably robust shell scripting. The heavy lifting is done by plash, which is a container engine.

Use cases

• Run non LTS packages in a LTS system
• Use Ubuntu packages in another distribution
• You don't have root access
• You don't like to use root access very often
• Install programs without cluttering your system
• Dont't bother about package names, caching meta data and other subtelities of your package manager: just type noapt <program-name>
• noapt ag is shorter than sudo apt install silversearcher-ag

Updating installed packages

No really nice solution yet: delete all build cache with plash purge and it will be rebuiled on demand.

The bad parts

• On my system 1.3 seconds startup time is just too much. That is absolutely optimizable, it comes mainly from slow python imports.
• I think fuse being slow is not too bad, the main work is expected to be done in /home, which is rbind mounted from container to host
• unionfs-fuse does not work perfectly with this setup: https://github.com/rpodgorny/unionfs-fuse/issues/78
• ~50 lines shell scripting
• It's not magic: the package runs in an isolated container where /home and /tmp is mounted to the host. It will not work with anything overly complicated.
