    VIM Help Page

    Hi,

    Hope this is the right place to post and ask my question.

    Problem: Cannot access the help pages inside VIM. I am running VIM version 8.2.2434 in Ubuntu 21.04.

    When I enter a :help in the command-line mode I get:

    E433: No tags file
    E149: Sorry, no help for help.txt.

    When I go to /usr/share/vim/vim82/doc I do see a help.txt though. I am not clear about this.

    I would appreciate some help.

    Thank you.

    Run vimtutor. That's a command.

    If :help doesn't work, I suspect you don't have the full vim install. There are multiple packaged versions - vim-tiny, vim-basic. I think you need the full, "vim" package for the most common stuff.

    Awesome. I did not know that command. I removed vim-tiny package and left the full one.

    May also ask you if you know why the color scheme that I defaulted on my .vimrc file in my /home directory and help section are only available when I open vim with root priviledges? This does not happen to me in CentOS for example, which I am more familiar with.

    Thanks again.

    What are the permissions on that ~/.vimrc file? Check with:
    Code:
    ls -al .vimrc

    Yet another reason that using "sudoedit" and not "sudo vim" or "sudo gedit" is the preferred method. Check permissions.

    CentOS and Ubuntu are different. They have different goals and subtle differences outside the package management differences. Isn't CentOS out of support?

    CentOS 6 is EOL/EOS. CentOS 7 is still good until 2024. CentOS 8 will switch to a rolling release model after 31 December 2021 and become "CentOS Stream 8".

    So instead of the old release chain / upstream-downstream relationship that looked like this:
    Fedora => Red Hat Enterprise Linux => CentOS

    ... we will now get this:
    Fedora => CentOS Stream => Red Hat Enterprise Linux

    That's one of the reasons why many former CentOS users are looking at alternatives so they could replace CentOS 8. "Rolling release" is just a big fat "NOPE!" in an Enterprise environment.

    The file belongs to the regular user in question (both uid and guid). Permissions are 755.

    Re: VIM Help Page

    Which release are you running? sudo behaves different on new Ubuntu releases than it did on olders releases and those are different from other linux distros default behavior. The parent directory permissions matter too. Please show the output.

    Re: VIM Help Page

    21.04 is too new for me. I think ssh behavior in Ubuntu changed. Track those changes down. I couldn't find any easily, but vaguely recall a discussion, somewhere, about the changes. I think the HOME directory was being set now, when it wasn't touched previously. Sorry I couldn't find a link.

    Please post text, not images. People with poor eyesight and some people pay for internet by the byte. 300 bytes is much nicer than 40Kb.
