How to degrade the repowerd

[suhuangjian]

Hello, I use Ubuntu Touch on Nexus6p

after I run the "apt-get upgrade" command,

The following packages have unmet dependencies:
 repowerd : Depends: repowerd-data (= 2018.04+ubports+0~20220810204931.7~1.gbp40e09b) but 2018.04+ubports+0~20220324230500.5~1.gbp47f5a2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

after run "apt-get -f install"

Unpacking repowerd-data (2018.04+ubports+0~20220810204931.7~1.gbp40e09b) over (2018.04+ubports+0~20220324230500.5~1.gbp47f5a2) ...
dpkg: error processing archive /var/cache/apt/archives/repowerd-data_2018.04+ubports+0~20220810204931.7~1.gbp40e09b_all.deb (--unpack):

W: No sandbox user '_apt' on the system, can not drop privileges
E: Sub-process /usr/bin/dpkg returned an error code (1)

I try run "apt-get install repowerd-data=2018.04+ubports+0~20220324230500.5~1.gbp47f5a2
", it is does not work.

enable the developer mode, computer can't find the adb devices

How can I fix this problem or reinstall the ubuntu touch

Please do not use apt at all, we are doing image-based upgrades, and have a channel concept:

• stable channel for all users
• release candidate (RC) for testers and devs, and ambitious users
• devel for developers

when using apt you would update to latest packages in devel, that might break your phone or has other complications. This is not a desktop distro!

Solution: Change to another channel briefly or reinstall UT with the installer. That will fix your issue.
