tldr doesn't work

[cburkins]

Love "tldr" on all my linux machines, so figured I would install it on Proxmox VE, which is just Debian 11 after all.

Doesn't seem to work, tldr pages aren't available

So did some googling, and tried to update the local cache of pages (which usually isn't needed). But that seems broken too...

root@red:~#                                                                                                                                                                                           
root@red:~# tldr --update                                                                                                                                                                             
tldr: /root/.local/share/tldr: createDirectory: does not exist (No such file or directory)

So I gave it a helping hand...

root@red:~# mkdir -p ~root/.local/share

I realize I kind of found my own solution, but I'd like to try and understand why this doesn't work as it should.

[BobhWasatch]

Just a guess since I've never heard of tldr before, but it would appear that Debian doesn't ship the actual pages, just the client app. The fact that apt shows the installed size as only 529 kB would tend to indicate that as well.

 

[BobhWasatch]

Also, Debian often documents required setup steps in /use/share/doc/<appname>

 

[cburkins]

Thanks for your quick reply, Bob. You didn't really ask, but "tldr" is an abbreviated version of the man pages. Shows you the "useful" version of super long man pages, kinda handy. And yes, you're right, usually, the first time you run tldr, it grabs (and caches) a copy of the popular tldr pages. On most distros, it just works. The first time you run it, you can see tldr is downloading a cache of pages (shows a few lines in the output).

On debian, can't figure out why it expects to find ~/.local/share and then refuses to create the direct on it's own... Will google a bit on that second point you made..... Also might create a quick generic Debian VM to see if stock debian behaves any differently than Proxmox.

Booted into a debian liveOS, and tried same. Same result as above. You have to manually create ~root/.local/share. Weird.

 

[BobhWasatch]

You can check bug reports at https://bugs.debian.org and can report a bug by using the "reportbug" tool.

FWIW, most of the time ~/.local/share will already have been created by your desktop environment. Most of the directories in ~/.local on this machine are related to desktop apps. Proxmox does not install a desktop so maybe that's why nobody else has reported this (I checked).

Doesn't seem to work, tldr pages aren't available
<snip>
So did some googling, and tried to update the local cache of pages (which usually isn't needed). But that seems broken too...

root@red:~#

So I gave it a helping hand...

root@red:~# mkdir -p ~root/.local/share                                                                                                                                                             
root@red:~#                                                                                                                                                                                         
root@red:~# tldr --update

I know this is from a couple of years ago, but did you really mean you did that mkdir?

mkdir -p ~root/.local/share

I found that it needed to name the tldr folder, as in:

mkdir -p ~root/.local/share/tldr

Otherwise I got the same error you originally noted there, when I tried to do the tldr --update.
