Solution: An error occurred during the request. Unable to proceed. Certificate "4510" has been revoked

I try to install this plugin in NC v26.
After git clone I have in admin-section Apps by Shifts buttons "Remove" and "Download and enable".
When I click to "Download and enable", I get error An error occurred during the request. Unable to proceed. Certificate "4510" has been revoked.

Now I understand, that the Name in Github "Shifts" with great "S" and Nextcloud don't see cumstoms_apps/shifts, it's cumstoms_apps/Shifts and download from apps.nextcloud.com 1.8.6 version (new is 1.9.0)

I have 2 Folder
*Shifts (1.9.0)
*shifts (1.8.6)

My bash skript:

cd custom_apps
rm -rf shifts/
rm -rf Shifts/
git clone https://github.com/csoc-de/Shifts.git
mv Shifts/ shifts/
cd shifts/
npm i
make dev-setup

Autor, please rename repo from Shifts to shifts.

For install from apps.nextcloud.com 1.8.6 you can errors remove, if you disable checks in your nextcloud:

1. An error occurred during the request. Unable to proceed. Certificate "4510" has been revoked
   Make comments in nextcloud/lib/private/Installer.php:241-259
   // Verify if the certificate has been revoked
/*$crl = new X509();
foreach ($rootCrts as $rootCrt) {
$crl->loadCA($rootCrt);
}
$crl->loadCRL(file_get_contents(__DIR__ . '/../../resources/codesigning/root.crl'));
if ($crl->validateSignature() !== true) {
throw new \Exception('Could not validate CRL signature');
}
$csn = $loadedCertificate['tbsCertificate']['serialNumber']->toString();
$revoked = $crl->getRevoked($csn);
if ($revoked !== false) {
throw new \Exception(
sprintf(
'Certificate "%s" has been revoked',
$csn
)
);
}*/

2. App "shifts" cannot be installed because it is not compatible with this version of the server
   Make comments in nextcloud/lib/private/Installer.php:130-137
   /*if (!\OC_App::isAppCompatible($version, $info, $ignoreMax)) {
throw new \Exception(
// TODO $l
$l->t('App "%s" cannot be installed because it is not compatible with this version of the server.',
[$info['name']]
)
);
}*/

of course, after installation, it is necessary to uncomment it back

The old certificate has been revoked since we ordered a new certificate.
Unfortunately, we are currently not able to publish the new version in the appstore since we're getting a signature error.
