+Are you tired of getting "Private key required to install a certificate‎‏‎‎‏‎" when trying to
+install a CA certificate under Android via the settings app?
+(It never works via the file browser directly. You have to go via, and I only paraphrase, as I only have GrapheneOS here, no LOS:
+Settings > something security > (more privacy and security?) > something login data/credentials/encryption > Install a certificate)
+
+Just check
+
+- The certificate must be *in PEM format*. If it is in DER, you get the error above.
+- The file extension must be `.crt` or `.cer`. Not `.pem`. Otherwise you get a different error.
