Can't install the installer (Pop!_OS Linux)

[mothwiingz]

Installing the installer packages. Copying the exact commands the site tells me to use, returns this error. It's step 2 specifically.

I'm on a Ubuntu based distro, if that helps

hi! What read-me are you following? The error message is moreover clear - redundant 0. The sudo wget -q - https://packages.adoptium.net/artifactory/api/gpg/key/public should do the job. hth.

[judovana]

also the sudo looks a bit weird, becasue Only the first command runs as root, but the last piped program - tee, is not. And it is the last command which is writing to the restricted file in /etc.
So it should be wget -q - https://packages.adoptium.net/artifactory/api/gpg/key/public | gpg --dearmor | sudo tee /etc/...

[judovana]

As for gpg --dearmor resulting to gpg: no valid OpenPGP data found. I hit the same. Afik it is not necessary here. So ... what readme are you following? ps: please, use copy-paste as text nenxt time, instead of image. TY!

I followed the commands you guys suggested, then continued with the process. Then, this happened:

Sorry if this is dumb and obvious, I've literally just started using Linux like two weeks ago. I'm also 15 and not very good at computer stuff in general

Thanx. It seems it will need a bit of tuning.

I'm not familiar with apt enough, but indeed it skipped the key import, so /etc/apt/trusted.gpg.d/adoptium.gpg is not there. You can skip the signature check if you must. Internet will help.

I had now tried the instructions as they are: https://adoptium.net/installation/linux/#_deb_installation_on_debian_or_ubuntu and it works out of the box on latest ubuntu. Even the -q0. The -q0 is essential to make the command sequence work as it is (sorry for missleading yu with 'jsut -q', but it is the error you had)

As your's wget do not know -q0 you may have weird wget. Tried on

wget --version
GNU Wget 1.21.4 built on linux-gnu.

-cares +digest -gpgme +https +ipv6 +iri +large-file -metalink +nls 
+ntlm +opie +psl +ssl/openssl 

and

wget --version
GNU Wget2 2.1.0 - multithreaded metalink/file/website downloader

+digest +https +ssl/gnutls +ipv6 +iri +large-file +nls -ntlm -opie +psl -hsts
+iconv +idn2 +zlib -lzma +brotlidec +zstd -bzip2 -lzip +http2 +gpgme

And they both had -q0

Pls try to log in as root (sudo su) and the execute the command from https://adoptium.net/installation/linux/#_deb_installation_on_debian_or_ubuntu

The Permission denied error is because you've added sudo to the wget command and not the bit of the pipeline that's trying to write the file into the location under /etc/apt. You need the elevated access for the tee command which is writing to the file. If you change your command to be wget -q0 - https://packages.adoptium.net/artifactory/api/gpg/key/public | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/adoptium.gpg > /dev/null then it should complete without the error. Alternatively you could run sudo su - first before running the command as-is on the installation page.

Note: Apologies if there's any typos in the line above - I've typed it manually from your screenshot. For future reference it's usually preferable for text to be put directly into the issues instead of screenshots so they can be cut and pasted more easily by anyone attempting to reproduce your issue - see https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks for some examples.

The need for sudo in these cases if you're not already root is mentioned in this section of the installer page that you referenced:
