<p>I tested this last night on a VM running 2.18.13 on Ubuntu 16.04
x64.<br>
</p>
<p>I commented out the lines in sources.list for the PPA to the
Ubuntugis archive and then issued the apt update command.</p>
<p>Checking the list, having excluded the Ubuntugis repository PPA,
there was no GDAL in the list of packages available for upgrade.</p>
<p>With apt upgrade, the packages were installed then 2.18.14 works
fine.</p>
<p>I would comment out the ubuntugis repository PPA lines in
sources.list or its descendants (list files in sources.list.d)
unless it actually tells you that a package isn't available, which
will presumably happen with the next point release in about 10
days, if it has been built to use the new version of GDAL.<br>

<p>Hi Patrick,</p>
<p>thanks for reply and suggestions.</p>
<p>I compile from source the development edition, but for server
and desktop I use repository.</p>
<p>I'll try your example if the issue continue for long time.</p>

is no mandated requirement to use the Ubuntugis repository for
2.18. The latest edition of 2.18 is available from the
non-ubuntugis Qgis repository for xenial. <br>
<br>
Do you have that option available to you? <br>
<br>
If you need the development edition (2.99) unfortunately the
developers are not supporting this on Xenial because of a
package dependency that is not supported by the Ubuntu
repositories for Xenial, even though it should in theory be
possible to get the required package(s) from another repository.
<br>
<br>
If you have used apt upgrade to update all the packages in your
system at once, including new ubuntugis packages, don't update
all the packages this way. Just update qgis by itself, and it
won't pull the new ubuntugis packages if it doesn't need them. <br>
<br>
The more technically astute might try commenting out the
ubuntugis repository from apt's sources.list files or fragments
before issuing the apt update command, or playing with Apt
pinning settings to prioritise repositories. <br>
<br>
Example: I installed Debian buster/testing and then attempted to
install Qgis 2.99 sid/unstable. This told me it needed a package
from Debian sid/unstable repositories. I changed the master
repository for debian to unstable and then apt update tells me
there are hundreds of new packages from unstable I could
install. I only want it to install the packages needed for qgis
so instead of running apt upgrade, I just run apt install qgis
etc to only pull the unstable packages it actually needs for
this installation, and then change the Debian master repository
back to buster. <br>
<br>
The above options may not suit every situation where ubuntugis
has to be used, obviously it does not suit your particular
requirement if you have to have the latest ubuntugis packages
for other reasons, however it may resolve the situation for
someone else. <br>
