Selective Updating

[dhempy]

Good Day:

I have an RPi4b that I've configured to do some webscraping with Python/Selenium/Brave. In order to get things working, I had to install a couple of older software distributions. The Pi is now telling me that software updates are available and I'm concerned that my older installations will get upgraded if I follow the standard "update/upgrade" everything protocol.

So I have 2 questions: 1) Is there a way to list which upgrades the system has identified? and 2) This would just be a confirmation ... I would then just apt -upgrade <software> to do individual upgrades correct?

Thanks.

P.S. Maybe there is a way to Exclude individual libraries from the complete update/upgrade methods?

there is a way to mark a package to be held. (not upgraded).
sudo apt-mark hold <package-name>

See apt-mark --help

After running 'apt update', when upgrades are available you should see:

NN packages can be upgraded. Run 'apt list --upgradable' to see them.

Thanks you both for answering! I will try them out and RTFM! Dan

To get a list of packages that can be upgraded

Code: Select all

apt list --upgradable

To upgrade a single package (will also pull in any dependencies)

Code: Select all

sudo apt install <package names(s)>

I don't know a way to limit "upgrade" to a list of packages other than holding some packages, but install will install the latest version even if an older version of the package is already installed.

There probably is a way. I just haven't looked hard enough.
