The message “One or more files did not pass the validity check!” is one that is happening quite often.
In order to be sure that what you download is not been tampered with and it is still the original application from the engineer, the pkgbuild maintainer from the AUR package can include an md5sum to add an extra layer of security.
Pacman will then check if these lines correspond with reality.
If they do not correspond, you get the error : One or more files did not pass the validity check!
Again this can happen with any application from AUR. Slimjet is just an example to help someone on the arcolinuxforum.com.
It does not mean that the download is corrupt or has malware in it. It often means the package has been updated but the md5sums have not been updated.
Like in “an other operating system” it is still our responsibility to decide whether we trust this download source and/or whether we want to install it. You can start reading the pkgbuild but for many of is it is utter Chinese.
packer slimjet --skipinteg
yaourt slimjet --m-arg --skipchecksums
or a variation of this
yaourt --m-arg --skipchecksums slimjet
yaourt --m-arg --skipchecksums -S slimjet
After the video I figured out that we can launch this application from the terminal as it needs to have admin access:
Admin access is needed to enable the sandbox for enhanced security. Choose 'Use sudo command' if you have sudo access on systems like ubuntu. Choose 'Use su command' if you have access to root account. If you don't have admin access, select 'Quit' and add the switch '--no-sandbox' to run Slimjet without sandbox (less secure).
1) Use sudo command
2) Use su command
After you did this in the terminal , you can launch it via the menu .
