Unable to install extensions

[someshkoli]

I'm constantlt getting this error while installing packages plugins. Happening for all packages

What could be the reason ?

[jorgebucaran]

Maybe the host is unavailable? Are you behind a firewall? Maybe curl is acting out. Do you have a .curlrc file? What's your operating system? Do you have a reason to believe you could be using an old version of tar or one that doesn't support any of these flags: -x -z, -f or -C?

The only reason this could happen is if we fail here:

fisher/fisher.fish

Lines 93 to 98 in ae423be

	if command curl $opts -Ss -w \"\" \$url 2>&1 | command tar -xzf- -C \$temp 2>/dev/null
	command cp -Rf \$temp/*/* $source
	else
	echo fisher: Invalid plugin name or host unavailable: \\\"$plugin\\\" >&2
	command rm -rf $source
	end

Hey @jorgebucaran, thanks for quick update. I checked the link and the tar was downloadable. Im running on arch linux Linux kasper 5.4.77-1-lts #1 SMP Tue, 10 Nov 2020 22:42:03 +0000 x86_64 GNU/Linux. and yes my tar does have above flags.

And about .curlrc, what should be the contents of that file ? I dont have rc for that

here's the link and its fully functional imo,

[jorgebucaran]

How did you install Fisher? Please note that I only support the installation method described in the README. If that's how you installed Fisher, please use fisher update to get the latest changes and try again.

Where did you start having this problem? Have you ever been able to install anything with Fisher at all?

[someshkoli]

I installed it from AUR and regarding tar command then all of the flags are operational.
Also fisher update gives the following:

[jorgebucaran]

@someshkoli Ah, you're using an older version of Fisher. I know because that's an old bug. Please upgrade to the latest Fisher and let me know if you still encounter this issue. Remove the AUR package and use:

curl -sL https://git.io/fisher | source && fisher install jorgebucaran/fisher

[someshkoli]

[jorgebucaran]

@someshkoli You're still not using the latest Fisher. I know because "fisher: invalid plugin name..." should be "fisher: Invalid plugin name..." instead ("invalid" is capitalized).

See, it's right here:

fisher/fisher.fish

Line 96 in ae423be

echo fisher: Invalid plugin name or host unavailable: \\\"$plugin\\\" >&2

[someshkoli]

How to clean previous versions completely ? :)

[jorgebucaran]

Yes, I think that might be the issue here. To remove Fisher: fisher remove jorgebucaran/fisher usually does it. But if you installed Fisher via pacman (which I don't support), you'll need to refer to your user manual. I don't know, how about pacman -Rns fisher?

[someshkoli]

I removed everything and installed via above method, Now even the version number is correct yet its giving me same error

[jorgebucaran]

@someshkoli Could you try again? I made some changes.

[someshkoli]

still not working :) maybe its something specific for my system

[jorgebucaran]

@someshkoli It could be. Try running this?

set --local temp (mktemp -d)
set --local url https://codeload.github.com/jorgebucaran/fisher/tar.gz/HEAD
curl --silent --write-out "" $url | tar --extract --gzip --directory $temp
ls $temp

[igalic]

i get:

Warning: Binary output can mess up your terminal. Use "--output -" to tell 
Warning: curl to output it to your terminal anyway, or consider "--output 
Warning: <FILE>" to save to a file.

after removing --silent.

This works:

meena@beastix ~> curl --output - --write-out "" https://codeload.github.com/jorgebucaran/fisher/tar.gz/HEAD | tar --extract --gzip --directory $temp -f -
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

100  5567  100  5567    0     0  22447      0 --:--:-- --:--:-- --:--:-- 22447
meena@beastix ~> ls -l /tmp/tmp.MW0chCId/
total 9
drwxr-xr-x  4 meena  wheel  7 Dec  9 18:17 fisher-HEAD/
meena@beastix ~> 

(and now we can add back the --silent ;)

This is on FreeBSD, btw

[jorgebucaran]

Does that mean --silent doesn't work on FreeBSD? @igalic

[igalic]

it does work, but i had to remove it to see what's failing

[jorgebucaran]

Warning: Binary output can mess up your terminal. Use "--output -" to tell

That's why we pipe it to tar. We shouldn't need to specify the --output flag unless we wanted to pipe the output to the terminal, which we never do.

Do you have a .curlrc file adding a new line to the output? We shouldn't need to use --write-out "".

Why do we need to use --output -? It's not needed on macOS or Linux. Is this a FreeBSD thing?

Why do we need to add -f - to tar? Is this also a FreeBSD thing?

And do you know how to set up a FreeBSD box free so I can test this?

[igalic]

it seems the only thing necessary we need is -f -, otherwise, FreeBSD tries to read from a Tape device :D

meena@beastix ~> curl --silent https://codeload.github.com/jorgebucaran/fisher/tar.gz/HEAD | tar --extract --gzip --directory $temp -f -
meena@beastix ~> rm -rf /tmp/tmp.MW0chCId/fisher-HEAD/
meena@beastix ~> curl --silent https://codeload.github.com/jorgebucaran/fisher/tar.gz/HEAD | tar --extract --gzip --directory $temp 
tar: Error opening archive: Failed to open '/dev/sa0'

re,

And do you know how to set up a FreeBSD box free so I can test this?

https://www.freebsd.org/where.html → https://download.freebsd.org/ftp/releases/VM-IMAGES/12.2-RELEASE/amd64/Latest/
see https://download.freebsd.org/ftp/releases/VM-IMAGES/README.txt for which image to get

if you wanna integrate FreeBSD into fisher's CI, Cirrus CI offers FreeBSD support: https://cirrus-ci.org/guide/FreeBSD/

[jorgebucaran]

I think we're good now @igalic @someshkoli. Please try one more time! 🙏

[igalic]

works! (for me ;)

[someshkoli]

@someshkoli It could be. Try running this?

set --local temp (mktemp -d)
set --local url https://codeload.github.com/jorgebucaran/fisher/tar.gz/HEAD
curl --silent --write-out "" $url | tar --extract --gzip --directory $temp
ls $temp

Still not working :"") some gzip error

[igalic]

Still not working :"") some gzip error

can you remove --silent so we can better see what's going on?

---

also, if possibly, please paste the output, instead of attaching an image. we're dealing entirely with text, turning that into an image makes it 100% less accessible

[jorgebucaran]

@someshkoli Answer this:

• OS name and version
• Fish version
• curl version
• tar version

[someshkoli]

OS:
LSB Version: 1.4
Distributor ID: Arch
Description: Arch Linux
Release: rolling
Codename: n/a
Fish: fish, version 3.1.2
CURL: curl 7.71.1
tar: tar (GNU tar) 1.32
XD

[someshkoli]

Got this error fixed with @jorgebucaran 's help <3.
My conda env was somehow messing with my normal env and curl was unable to fetch CA certs

[akhiljalagam]

I just removed my ~/.curlrc with backup and it worked.

[cosmojg]

Leaving a tip here for future me: make sure that you have gzip installed! 😵‍💫
