Hello friends, this is my first thread, sorry for ignorance, I researched a lot here in the forum and did not find the solution. I've had my n9 for 6 years, and every once in a while I flash him (flasher -f -F DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin -F DFL61_HARMATTAN_40.2012.13-7.LTA_EMMC_LTA.bin --erase-user-data). But since the last flash last week, I can not install some applications. Apparently the error is 255 (setup interrupted)Operation failed: E: sub-process Usr/bin/dpkg returned an error code (255). I must have flashed some 50 times my n9 during this 6 years and always managed to install my apps. But this time around 30 percent of the apps I want to install is giving this error. Do you have any idea what's wrong?
