Legacy Netrunner 17
1

Hello,

I have install Netrunner 17 in 8Gb USB in persistent mode.

How can I upgrade in this USB? is safe without upgrade? How can I install Greece language and characters?

This solve the problem if done the Upgrade?
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get remove --purge linux-image-X.X.XX-XX-generic
dpkg --get-selections | grep linux-image
dpkg -l linux-* | awk ‘/^ii/{ print $2}’ | grep -v -e uname -r | cut -f1,2 -d"-" | grep -e [0-9] | grep -E “(image|headers)” | xargs sudo apt-get -y purge

Upgrade done as this?
sudo apt-get update && sudo apt-get upgrade

I wait for your answer…
thanks a lot…

Persistence is typically user data only, the OS would still be read only.
What method did you use to create persistence?

This I use “Universal USB Installer - Easy as 1 2 3” and is the best.

Persistency works for the full system. Though I suggest only upgrading the system without kernel. As kernel upgrade needs manual adaptation on the live media itself. (where apt-get cannot reach)
