Error installing Olympus on PopOS

[glacial adder]

so, im trying to install Olympus on PopOS, and every time i try to run the install script, this error message in picture 1 appears.
in pictures 2 and 3 theres the install.sh file.

Script unreadable per discord compression

Imo install the flatpak

[glacial adder]

ah wait let me screenshot the line

[quaint barn]

(deck@steamdeck ~)$ d=543
(deck@steamdeck ~)$ echo "${d:0:1}"
5

well, is it running the script using bash, or some other shell?

[glacial adder]

im using the sh command, am still pretty new to linux xd

[quaint barn]

(deck@steamdeck ~)$ sh
sh-5.2$ d=543
sh-5.2$ echo "${d:0:1}"
5
sh-5.2$ 

nevermind, even sh can do it

[glacial adder]

so this instead of line 41?

[torn lark]

nooo

anyway remove sh and just write the file name hopefully

i was wondering where the code block is from but apparently that's maddie running things

[quaint barn]

yeah, ${d:0:1} is supposed to extract the first character of d

so the intention here is for the script to work if you type "yes" as opposed to just "y"

[torn lark]

or write bash instead of sh i think

maybe

[quaint barn]

hopefully running the file itself should use bash

[glacial adder]

ah nvm just used bash

it worked

tysm tho!

[torn lark]

i am clueless about this but ai tells me that sh uses a different shell on ubuntu and the likes

Dash?

Interesting never heard of it

[quaint barn]

huh yeah, mine points to bash (I'm on SteamOS)

[torn lark]

i think that follows from 'deck@steamdeck'

[quaint barn]

same from a Debian box

maddie@box:~$ file -h /bin/sh
/bin/sh: symbolic link to dash
maddie@box:~$ sh
$ d=14423
$ echo "${d:0:1}"
sh: 2: Bad substitution
$ 

[torn lark]

I remember trying to run shell scripts with sh once no wonder it didn't work

[quaint barn]

apparently recent Ubuntu and Debian versions have sh redirect to dash instead of bash

and PopOS is an Ubuntu derivative
