Linux SDK Install Problem

I tried to install the 2022.3, 2022.6 and 2023.0 sdks under linux without success.
Can anyone point out what is going wrong?
I used the following commands:

plcncli --version  
plcncli 21.0.0 LTS (21.0.0.489)  
  
  
> sudo plcncli install sdk -d /usr/local/sdk_2022.3/ -p pxc-glibc-x86_64-axcf2152-image-sdk-cortexa9t2hf-neon-axcf2152-toolchain-2022.6.sh

I tried to update the plcncli to 2022.6

>plcncli --version  
  
plcncli 22.6.0 (22.6.0.1153)  
  
>udo plcncli install sdk -d /usr/local/sdk_2022.6/ -p pxc-glibc-x86_64-axcf2152-image-sdk-cortexa9t2hf-neon-axcf2152-toolchain-2022.6.sh

Hello svenplc,
please check if you set the permissions (write and execute) for “pxc-glibc-x86_64-axcf2152-image-sdk-cortexa9t2hf-neon-axcf2152-toolchain-2022.6.sh” .
