I started a docker container and then installed ubuntu-advantage-tools in the container, although had following error messages during the installation, i assume it does not matter.

debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 78.)
debconf: falling back to frontend: Readline
debconf: unable to initialize frontend: Readline
debconf: (Can't locate Term/ReadLine.pm in @INC (you may need to install the Term::ReadLine module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.34.0 /usr/local/share/perl/5.34.0 /usr/lib/x86_64-linux-gnu/perl5/5.34 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.34 /usr/share/perl/5.34 /usr/local/lib/site_perl) at /usr/share/perl5/Debconf/FrontEnd/Readline.pm line 7.)
debconf: falling back to frontend: Teletype

After that, i can get following commands run correctly:

# pro --version

However, other more commands with following exceptions:

# cat /proc/version_signature
cat: /proc/version_signature: No such file or directory

# pro security-status

Looks like the kernel failed to launch the pro client somehow.

Anyone met same problem? Thanks a lot.

Please [edit](https://askubuntu.com/posts/1438996/edit) your question and add the output of `cat /proc/version_signature`?

Thank you for comments. The output is `No such file or directory`.

Add the output of `uname -a` as well, please. Use [code formatting](https://askubuntu.com/editing-help#code) for commands and command output.

`4.12.14-120-default` doesn't look like any current Ubuntu kernel. Ah, I see you're doing this in a container. Then the kernel is shared with the host, so it seems the only thing to do here if you really need UA in a container (why, though?) is to run in an Ubuntu host.

@muru Oh... I see, then the reason here is that ***the kernel is shared with the host***. I just want to taste the UA and unable to find a Ubuntu hosted machine, so I've thought to test UA in a container.

i managed to get a ubuntu hosted machine, this time i got following problem: `# pro --help Failed to access URL: https://contracts.canonical.com/v1/resources?architecture=amd64&kernel=5.15.0-52-generic&series=jammy Cannot verify certificate of server Please check your openssl configuration. ` how to resolve it?

@jake You need to make sure that you have an Ubuntu One account and then you need to get your tokens from your account that will install the certs with it as well. Once you have your account the dashboard will show you your token. https://ubuntu.com/pro/dashboard and there it should show you the command you run to attach that system to pro.

@Terrance I've already received one token. As I mentioned in above comment, I got the error with command `#pro --help`, I assume failure of this command indicates something wrong which blocks me moving forward (i.e. `#pro atach [token]` etc) the next step, this error must be resolved. Now, i tried more other command like `#pro security-status` , same failure message shown. Again, i tried `#pro attach [my token i received]`, the error message is `Failed to attach machine. See https://ubuntu.com/pro` ( as i supposed though).

Are you using an LTS installation? Also, is your kernel one that either comes with the LTS release or one of the HWE? Anything outside of those you will not be able to attach the system to pro.

jake

@Terrance Yes I am using an LTS installation as `cat /etc/os-release` shows following information `PRETTY_NAME="Ubuntu 22.04.1 LTS" VERSION="22.04.1 LTS (Jammy Jellyfish)"`; And also, `uname -r` cmd shows `5.15.0-52-generic` thus I assume the kernel version is fine to support UA.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
