I'm running a VPS with Ubuntu 18.04 and experience similar problems and get quite long error messages (see screenshot). It's pretty annoying to get those errors when switching panels and a maybe a beginner user would be get very scared to use the app afraid that could mess up the database operations...
Considering my alternatives 1) Upgrade to the latest version from the website. The problem is that I would have to update manually... not very convenient for the security maintenance... 2) Do the fix indicated by https://devanswers.co/problem-php-7-2 -phpmyadmin-warning-in-librariessql-count/. The problem would be that whenever phpmyadmin got updated the fix would be gone as well. If backporting those compatibility fixes with php 7.2 shipped with the latest phpmyadmin 4.8 series is not convenient, what about offering on the repositories an extra package with the phpmyadmin 4.8 series so that users could get security updates automatically (in that way people who are happy with 4.6 series don't need to upgrade if they so wish)? Thanks a lot for the great effort of the development/maintainers community. ** Attachment added: "Screenshot_20180914_215602.png" https://bugs.launchpad.net/ubuntu/+source/phpmyadmin/+bug/1767361/+attachment/5188872/+files/Screenshot_20180914_215602.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767361 Title: 4.6.6deb5 not working on Bionic as PHP 7.2 is default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/phpmyadmin/+bug/1767361/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
