Hi I am trying to install software on PureOS 10 but getting errors below. Would anyone have advice? thanks
$ sudo snap install youtube-dl-pro
2025-03-09T18:47:41-06:00 INFO Waiting for automatic snapd restart…
error: cannot perform the following tasks:
As the error message says, you may want to check what version of snap you have and try to update it first. Try sudo apt update && sudo apt upgrade && sudo apt info snap and then see if your installation works. You can also check if there is some internal snap update thing needed: sudo snap refresh (if I got it right)
thanks for your help!!
$ sudo apt update && sudo apt upgrade && sudo apt info snap

Interesting. Those clear some uncertainties.
Looking at this, it has popped up before (see for instance here or online). There’s something funny happening with that.
(I avoid snap. Are you sure you can’t use a flatpak alternative?)
im up for trying flatpak - how can i install this?
Install Flatpak with sudo apt install flatpak and then setup Flathub as source with flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
Then install the app that you want from Flathub.org catalog - there is a blue “Install” button that gives you the correct command (in this case, unless you want t check any of the alternatives: flatpak install flathub io.github.JaGoLi.ytdl_gui)
It looks like you are using snapd from a standard “deb” install. Ubuntu moved to having snapd be a snap itself. That ensures that snapd is always up-to-date and newer snaps depend on that.
If you wish, you could change your snapd to be a snap. The current snapd is version 2.67.1
snap find snapd | grep ^snapd
snapd 2.67.1 canonical** snapd Daemon and tooling that enable snap packages
You would simply:
sudo snap install snapd
You might want to do a
snap list
both before and after.
After the snapd snap is installed you might need to uninstall the standard deb version of snapd by doing a “sudo apt remove snapd”.
All of the above should be able to be reversed (by adding back in the deb snapd … and removing the snap snapd) if there is an issue.
[Edit:
yt-dlp is the now-recommended fork of youtube-dl. (It’s even recommended on the youtubedl subreddit).
I would like to add that youtube-dl-pro is a proprietary application.
There are other youtube-dl applications that are distributed as snaps. They aren’t very up-to-date. The standard one is youtube-dl which is dated 2022-08-26. While it purports to be from GitHub - joedborg/youtube-dl: Command-line program to download videos from YouTube.com and other video sites … I haven’t verified that.
Personally, I would rather use yt-dlp … but, even then, I haven’t verified the author of that snap, but it is purportedly Graham Morrison from Canonical. This build is dated:
2025.01.26-8-g03c3d7057 2025-02-06 (822) 128MB
Be careful of snaps where you don’t trust the authors.
