# Q: Ubuntu phased updates
|
|
|
|
Recently, during the normal software upgrade process (i.e., apt upgrade or apt dist-upgrade) I started getting messages like this:
|
|
|
|
```
|
|
[...]
|
|
The following packages have been kept back:
|
|
[...]
|
|
0 upgraded, 0 newly installed, 0 to remove and [...] not upgraded.
|
|
```
|
|
What are my options?
|
|
|
|
## A: Phased Updates are a safety feature
|
|
Some users get the upgraded packages first, and have the ability to report broken package, instead of everybody getting a broken package at once and millions of users scratching their heads.
|
|
It's there for your protection. Don't try to outsmart it.
|
|
|
|
Kept-back packages due to Phased Updates will automatically resolve themselves, download, and install over a week or so.
|
|
Most users should DO NOTHING. It's not broken. Don't try to force upgrades. Just be patient and let the system work.
|
|
|
|
## Diagnosis -- how to tell if Phased Updates is the culprit:
|
|
|
|
It's easy. Run apt-cache policy <packagename> on one of your held back packages. Look for the 'phased' percentage. It's only present if the package is currently phasing.
|
|
|
|
```
|
|
$ apt-cache policy gir1.2-gstreamer-1.0
|
|
gir1.2-gstreamer-1.0:
|
|
Installed: 1.20.3-0ubuntu1
|
|
Candidate: 1.20.3-0ubuntu1
|
|
Version table:
|
|
