Basic Pleskian
Regards community,
this is my problem:
When trying to reach my plesk panel website (https://domain.com:8443/) plesk returns a website saying "Server Error 502 Bad Gateway Web server received an invalid response while acting as a gateway or proxy server.". So I can't login to my webpage.
Furthermore I have received three E-Mails stating:
/usr/bin/sw-engine: symbol lookup error: /usr/bin/sw-engine: undefined symbol: _ZNK3APS4Meta14ScreenshotInfo4pathB5cxx11Ev
this is what may have caused it:
I was upgrading my ubuntu server with distupgrade.helper.ubt14-ubt16.x64.sh (according to your article see here). Well then everything went wrong and the install could not finish and everything was broken (websites, services and plesk). The server was still up with ssh. So I choose to do the following steps (see source):
apt-get update
apt-get dist-upgrade
apt-get autoremove
apt-get autoclean
update-grub
So this went well and I've had Ubuntu 16 up and running. Then I used my last plesk backup and restored it completely. So all websites came back online but not on port 443. So I enabled apache module ssl. Then everything seemed ok .... until today (even plesk was fine).
this is what I tried to do, to solve my problem:
Checked a help article: Unable to access Plesk: symbol lookup error: /usr/bin/sw-engine: undefined symbol
Which suggested me to check libaps. Which I've did:
Version: 1.0.8-ubuntu14.04.798670.16071418 is installed right now.
Where do I get the 16.04. version? Is this the correct version for my system:
http://autoinstall.plesk.com/PSA_17...s_1.0.8-ubuntu16.04.798670.16061715_amd64.deb
This is my system:
Can you help me please?
Thank you all a lot!
