I upgraded my system from fedora 25 to 26 and now mendeley desktop fails to open. I was using the version 1.16 (with latest updates). Even the latest version (1.17.10) does not work. When I run it from the terminal this is the message I'm getting:QSslSocket: cannot resolve CRYPTO_num_locksQSslSocket: cannot resolve CRYPTO_set_id_callbackQSslSocket: cannot resolve CRYPTO_set_locking_callbackQSslSocket: cannot resolve ERR_free_stringsQSslSocket: cannot resolve sk_new_nullQSslSocket: cannot resolve sk_pushQSslSocket: cannot resolve sk_freeQSslSocket: cannot resolve sk_numQSslSocket: cannot resolve sk_pop_freeQSslSocket: cannot resolve sk_valueQSslSocket: cannot resolve SSL_library_initQSslSocket: cannot resolve SSL_load_error_stringsQSslSocket: cannot resolve SSL_get_ex_new_indexQSslSocket: cannot resolve SSLv2_client_methodQSslSocket: cannot resolve SSLv23_client_methodQSslSocket: cannot resolve SSLv2_server_methodQSslSocket: cannot resolve SSLv23_server_methodQSslSocket: cannot resolve X509_STORE_CTX_get_chainQSslSocket: cannot resolve OPENSSL_add_all_algorithms_noconfQSslSocket: cannot resolve OPENSSL_add_all_algorithms_confQSslSocket: cannot resolve SSLeayQSslSocket: cannot resolve SSLeay_versionQSslSocket: cannot call unresolved function SSLeayQSslSocket: cannot call unresolved function CRYPTO_num_locksQSslSocket: cannot call unresolved function CRYPTO_set_id_callbackQSslSocket: cannot call unresolved function CRYPTO_set_locking_callbackQSslSocket: cannot call unresolved function SSL_library_initQSslSocket: cannot call unresolved function SSLv23_client_methodQSslSocket: cannot call unresolved function sk_numI have openssl, openssl-devel (version 1:1.1.0f-7), qt and qtwebkit installed. Cannot figure out the problem. I know I should ask this question in Mendeley support and I did but there is no response. As such, the support site has some problems.
Mendeley desktop does not start in Fedora 26
fedora;openssl;ssl
this works for me on fedora 26:sudo dnf install compat-openssl10-devel
