openssl package

should I downgrade libssl1.1 to libssl1.0 to install npm

Asked by Pachuca

I posted this on askubuntu https://askubuntu.com/questions/1258870/ubuntu-20-04-should-i-downgrade-libssl1-1-to-libssl1-0-to-install-npm

Just trying to install npm and the solution I get from aptitude is to downgrade the versions. What impact does that have on my ubuntu 20 LTS if I downgrade?

As already shown on https://askubuntu.com/questions/1258870/ubuntu-20-04-should-i-downgrade-libssl1-1-to-libssl1-0-to-install-npm the root cause of your problem is the usage of software from a PPA

You wrote that you are running Ubuntu 20.04, but the foreign version of libssl1.1 that causes the problem is for Ubuntu 18.04.

For diagnostic purposes please provide the output that you receive for the commands (to be executed in a terminal window):

uname -a
lsb_release -crid
sudo apt update
apt-cache policy libssl-dev libssl1.1

Remark: it seems to me that the required downgrade is not from ibssl1.1 to libssl1.0 but only from libssl1.1 version 1.1.1g to libssl1.1 version 1.1.1f

Thanks for your reply, that clears up a lot for me. I didn't see the reply on askubuntu until now. Is there anyway to avoid downgrading or is that the only way I can install npm?

There is something strange in your settings with respect to the PPA from ondrej sury.
You have libssl1.1 installed from that PPA, but that PPA is no more listed in the output of apt-cache.

What have you done? Have you enabled and later disabled a PPA? Which PPA did you have activated? Or have you manually installed a package from there?

What is the output of
sudo apt update
(already asked before, why didn't you show that output?) and the output of
grep -i ppa /etc/apt/sources.list /etc/apt/sources.list.d/*.list

If you want to avoid downgrading, you probably can re-enable the PPA that you had, and it might instaöl libssl1.1 version 1.1.1g-1+ubuntu20.04.1+deb.sury.org+1 and this should allow installing the required dependencies for npm

I usually just do a fresh install for new LTS releases to avoid all of this, but this time I decided to upgrade from bionic to focal. Afterwards all my PPA's were disabled by default. I just assumed this was part of the process. Would enabling the ppa fix things?

I suggest that you re-enable http://ppa.launchpad.net/ondrej/php/ubuntu with focal as release name.

sudo gedit /etc/apt/sources.list.d/ondrej-ubuntu-php-bionic.list
remove the comment indicator ('# ') in front of "deb" and replace "bionic" by "focal" in the "deb-src" line.

Then execute
sudo apt update
apt list --upgradeable

What output do you receive? I assume that it will show a possible uprade of libssl packages.

Yes, it shows the upgrade like this:

so I did sudo apt upgrade && sudo apt dist-upgrade. That fixed the problem for me. I'm able to install npm now. Thank you so much for your help!! I wish you all the best and keep up the good work you're doing here. I'm pretty new to Linux if you couldn't tell. I'm coming from windows so I really appreciate you being patient with me and helping me fix this, probably trivial problem for you, kind of complex for me lol.
