Adjustments for COSMIC users on Synex

Announcements | General

With the COSMIC update to version 1.1.0 on Synex, there are two specific adjustments worth applying once on systems installed from earlier images. They apply to both the stable and semi-rolling branches.

pop-launcher

The first COSMIC images included a version of pop-launcher with a higher numbering than the current versioning scheme. Since APT does not perform downgrades automatically, it's best to apply the change manually.

On the stable branch:

sudo apt install --allow-downgrades pop-launcher=1.1.0+synex1

On semi-rolling:

sudo apt install --allow-downgrades pop-launcher=1.1.0+synex1+sr1

The binary is functionally the same, so this step is a matter of tidiness: it aligns the installed version with the one in the repository. It is not mandatory, and if you skip it the desktop keeps working normally.

cosmic-monitor

COSMIC version 1.1.0 adds a new component: the system monitor. Being a new package, it is not installed automatically during an upgrade. If you want to add it:

sudo apt install cosmic-monitor

Final words

Both adjustments are optional and one-time only. Future images already include the correct versioning and components, so these steps are only necessary for those coming from earlier versions of COSMIC.
